Invention of computers was the highest moment of the development of the USA high-tech industry, the area which defined the progress of high-tech as a whole. This is an area were the USA really has been the greatest nation of the world. Real "shining city on the hill". The USA gave the world great programmers, hardware designers, network architects and managers. Those unique conditions, when the whole country was a large Silicon Valley of the world, were destroyed by neoliberal transformation of society and, especially, neoliberal transformation of higher education (when university were transformed into for profit corporation for the university elite) started in 80th and getting to full speed after 2001.
When ENIAC was declassified in 1946 ( it made the front page of the New York Times) the computer revolution was put into fast motion. As early as 1952 during the presidential elections night, Univac computer correctly predicted the winner. While chances were 50% ;-), this was an impressive introduction of computers into mainstream society. IBM, DEC, CDC and later Intel, HP, Apple and Dell emerged as the leading producers of hardware. With the advent of microprocessors all major CPU, Include Intel x86 and Motorola 68000, PowerPC, etc were US designed. The USA programmers created all major world operating systems such as System/360, Multics, VM/CMS, VAX/VMS, Unix, CP/M, DOS, Windows, System 7, OS 7, major linux distributions, such as Red Hat and Debian, Android. in 1967 they wrote the first hypervisor ( CP-67; later renamed to CP/CMS was available to IBM customers from 1968 to 1972, in source code form without support). In 1072 the shipped first commercial hypervisor VM/370. Later they create a series of impressive offering in this area too such as VirtualBox and VMware.
History is written by the winners and computer history of XX century was definitely written in the USA. If we assume that the professional success is a mixture of natural abilities, hard labor and luck (including being born at the right place at right time), as in Malcolm Gladwell suggested in his unscientific, but now popular The 10,000 Hour Rule it is clear that the US scientists have has all those three components. But they were not alone -- conditions is GB, Germany and France were not bad iether. While we should take Gladwell findings and his 10000 rule with a grain of slat, it point to one interesting observation. Most those that I mention below were born between 1920 and 1955 -- a window of opportunity in computer science which since then is virtually closed. It is similar to 1830-1840 window for titans of Gilded Age such as Rockefeller (1939), Carnegue(1835), Gould(1836), J.P Morgam(1837) that Gladwell mentioned. "No one—not rock stars, not professional athletes, not software billionaires, and not even geniuses—ever makes it alone", writes Gladwell.
At the same time it is important to see this history not as "people, places and events" but also via artifacts, be it machines, programs or interviews of pioneers. This part of history is badly persevered in the USA. Moreover there is a trend of Dumbing down history of computer science. As Donald Knuth remarked ( Kailath Lecture and Colloquia):
For many years the history of computer science was presented in a way that was useful to computer scientists. But nowadays almost all technical content is excised; historians are concentrating rather on issues like how computer scientists have been able to get funding for their projects, and/or how much their work has influenced Wall Street. We no longer are told what ideas were actually discovered, nor how they were discovered, nor why they are great ideas. We only get a scorecard.
Similar trends are occurring with respect to other sciences. Historians generally no prefer "external history" to "internal history", so that they can write stories that appeal to readers with almost no expertise.
Historians of mathematics have thankfully been resisting such temptations. In this talk the speaker will explain why he is so grateful for the continued excellence of papers on mathematical history, and he will make a plea for historians of computer science to get back on track.
History is always written by the winners, and that means right now it is written by neoliberals. Dumping down history of computer science is just application of neoliberalism to particular narrow field. The to way an essence of neoliberal history is "to dumb down everything". Dumbing down is a deliberate lowering of the intellectual level of education, literature, cinema, news, and culture. Deliberate dumbing down is the goal.
They use power of vanity to rob us of vision which history can provide. Knuth lecture "Let's Not Dumb Down the History of Computer Science" can be viewed at Kailath Lecture and Colloquia. He did important point that historical errors are as important as achievement, and probably more educational. In this "drama of ideas" (and he mentioned high educational value of errors/blunders of Linux Torvalds in design of Linux kernel) errors and achievement s all have their place and historical value. History gives people stories that are much more educational then anything else. that's that way people learn best.
Giants of the field either were US citizens or people who worked in the USA for a long time. Among them:
Those people mentioned above are all associated with the USA. And I named just a few about work of which I personally know... The USA computer science research was often conducted in close collaboration with British computer scientists which also made some significant contributions (some of the most impressive IBM compilers were actually designed and implemented in Britain) but the leadership role of the USA was indisputable. CACM was always more important publications then Computer Journal.
Large part of this unique technology culture was destroyed via outsourcing frenzy which started around 1998, but the period from approximately 1950 till approximately 2000 was really the triumph of the US computer engineering. Simultaneously this was a triumph of New Deal policies. When they were dismantled (starting from Reagan or even Carter), and neoliberalism became the ruling ideology, computer science quickly was overtaken by commercial interests and became very similar to economics in the level of corruption of academics and academic institutions.
But that did not happened overnight and the inertia lasted till late 90th.
Firms also did not escape this transformation into money making machines with IBM as a primary example of the disastrous results of such transformations which started under "American Express"-style leadership of Lou Gerstner. The first of financial shenanigans, who became CEO of a major technical company. And who will later destroy several other major US computer companies. In the interests of shareholders and personal bonuses ;-). See IBM marry Linux to Outsourcing.
Here is the timeline modified from History of Computer Science
In 1949 The U.S. Army and the University of Illinois jointly fund the construction of two computers, ORDVAC and ILLIAC (ILLInois Automated Computer). The Digital Computer Laboratory is organized. Ralph Meagher, a physicist and chief engineer for ORDVAC, is head. 1951 ORDVAC (Ordnance Variable Automated Computer), one of the fastest computers in existence, is completed. 1952 ORDVAC moves to the Army Ballistic Research Laboratory in Aberdeen, Maryland. It is used remotely from the University of Illinois via a teletype circuit up to eight hours each night until the ILLIAC computer is completed
Grace Murray Hopper (1906-1992) invented the notion of a compiler, at Remington Rand, in 1951. Earlier, in 1947, Hopper found the first computer "bug" -- a real one -- a moth that had gotten into the Harvard Mark II. (Actually, the use of ``bug'' to mean defect goes back to at least 1889.). The first compiler was written by Grace Hopper, in 1952, for the A-0 System language. The term compiler was coined by Hopper. History of compiler construction - Wikipedia, the free encyclopedia
In a famous paper that appeared in the journal Mind in 1950, Alan Turing introduced the Turing Test, one of the first efforts in the field of artificial intelligence. He proposed a definition of "thinking" or "consciousness" using a game: a tester would have to decide, on the basis of written conversation, whether the entity in the next room responding to the tester's queries was a human or a computer. If this distinction could not be made, then it could be fairly said that the computer was "thinking".
In 1952, Alan Turing was arrested for "gross indecency" after a burglary led to the discovery of his affair with Arnold Murray. Overt homosexuality was taboo in 1950's England, and Turing was forced to take estrogen "treatments" which rendered him impotent and caused him to grow breasts. On June 7, 1954, despondent over his situation, Turing committed suicide by eating an apple laced with cyanide.
In the same 1952 ILLIAC, the first computer built and owned entirely by an educational institution, becomes operational. It was ten feet long, two feet wide, and eight and one-half feet high, contained 2,800 vacuum tubes, and weighed five tons.
In the same 1952 IBM developed first magnetic disk. In September 1952, IBM opened a facility in San Jose, Calif.—a critical moment in the story of Silicon Valley. The company set to work developing a new kind of magnetic memory for its planned Model 305 Ramac (Random Access Method of Accounting and Control), the world's first "supercomputer."
In 1952 Univac correctly predicted the results of presidential elections in the USA. Remington Rand seized the opportunity to introduce themselves to America as the maker of UNIVAC – the computer system whose name would become synonymous with computer in the 1950s. Remington Rand was already widely known as the company that made the Remington typewriters. The company bought out the struggling Eckert-Mauchly Computer Corporation in 1950. Pres Eckert and John Mauchly had led the ENIAC project and made one of the first commercially available computer, UNIVAC. See Computer History Museum @CHM Have you got a prediction for us, UNIVAC
The IBM 650 Magnetic Drum Data Processing Machine was announced 2 July 1953 (as the "Magnetic Drum Calculator", or MDC), but not delivered until December 1954 (same time as the NORC). Principal designer: Frank Hamilton, who had also designed ASCC and SSEC. Two IBM 650s were installed at IBM Watson Scientific Computing Laboratory at Columbia University, 612 West 116th Street, beginning in August 1955.
Edsger Dijkstra invented an efficient algorithm for shortest paths in graphs as a demonstration of the ARMAC computer in 1956. He also invented an efficient algorithm for the minimum spanning tree in order to minimize the wiring needed for the X1 computer. (Dijkstra is famous for his caustic, opinionated memos. For example, see his opinions of some programming languages).
In 1956 IBM 305 RAMAC was announced. It was the first commercial computer that used a moving head hard disk drive (magnetic disk storage) for secondary storage. The 305 was one of the last vacuum tube computers that IBM built. The IBM 350 disk system stored 5 million 8-bit (7 data bits plus 1 parity bit) characters. It had fifty 24-inch-diameter (610 mm) disks.
The same year Case University Computing Center got IBM 650 and the same year Donald Knuth entered this college and he managed to start working at the Case University Computing Center. That later led to creation of his three volume series the Art of Computer Programming -- the bible of programming as it was called.
On October 4, 1957, the first artificial Earth satellite Sputnik was launched by USSR it into an elliptical low Earth orbit. In a way it as a happenstance due to iron will and talent of Sergey Korolev, a charismatic head of the USSR rocket program (who actually served some years in GULAG). But it opened a new era. The ILLIAC I (Illinois Automatic Computer), a pioneering computer built in 1952 by the University of Illinois, was the first computer built and owned entirely by a US educational institution, was the first to calculated Sputnik orbit. The launch of Sputnik led to creation NASA and indirectly of the US Advanced Research Projects Agency (DARPA) in February 1958 to regain a technological lead. It also led to dramatic increase in U.S. government spending on scientific research and education via President Eisenhower's bill called the National Defense Education Act. This bill encouraged students to go to college and study math and science. The students' tuition fees would be paid for. This led to a new emphasis on science and technology in American schools. In other words Sputnik created building blocks which probably led to the general establishment of the way computer science developed in the USA for the next decade of two. DARPA latter funded the creation of the TCP/IP protocol and Internet as we know it. It also contributed to development of large integral circuits. The rivalry in space, even though it had military reasons served as tremendous push forward for computers and computer science.
John Backus and others developed the first complete complier -- FORTRAN compiler in April 1957. FORTRAN stands for FORmula TRANslating system. Heading the team is John Backus, who goes on to contribute to the development of ALGOL and the well-known syntax-specification system known as BNF. The first FORTRAN compiler took 18 person-years to create.
LISP, a list-processing language for artificial intelligence programming, was invented by John McCarthy about 1958. The same year Alan Perlis, John Backus, Peter Naur and others developed Algol.
In hardware, Jack Kilby (Texas Instruments) and Robert Noyce (Fairchild Semiconductor) invented the integrated circuit in 1959.
In 1959 LISP 1.5 appears. The same year COBOL is created by the Conference on Data Systems and Languages (CODASYL).

Operating systems saw major advances. Fred Brooks at IBM designed System/360, a line of different computers with the same architecture and instruction set, from small machine to top-of-the-line. DEC designed PDP series. The first PDP-1 was delivered to Bolt, Beranek and Newman in November 1960, and formally accepted the next April. The PDP-1 sold in basic form for $120,000, or about $900,000 in 2011 US dollars. By the time production ended in 1969, 53 PDP-1s had been delivered.At the end of the decade, ARPAnet, a precursor to today's Internet, began to be constructed.
In 1960 ALGOL 60, the first block-structured language, appears. This is the root of the family tree that will ultimately produce the Pl/l, algol 68, Pascal, Modula, C, Java, C# and other languages. ALGOL become popular language in Europe in the mid- to late-1960s. Attempts to simplify Algol lead to creation of BASIC (developed c. 1964 by John Kemeny (1926-1992) and Thomas Kurtz (b. 1928)). It became very popular with PC revolution.
The 1960's also saw the rise of automata theory and the theory of formal languages. Big names here include Noam Chomsky and Michael Rabin. Chomsky introduced the notion of context free languages and later became well-known for his theory that language is "hard-wired" in human brains, and for his criticism of American foreign policy.
Sometime in the early 1960s , Kenneth Iverson begins work on the language that will become APL--A Programming Language. It uses a specialized character set that, for proper use, requires APL-compatible I/O devices. APL is documented in Iverson's book, A Programming Language published in 1962
In 1962 ILLIAC II, a transistorized computer 100 times faster than the original ILLIAC, becomes operational. ACM Computing Reviews says of the machine, "ILLIAC II, at its conception in the mid-1950s, represents the spearhead and breakthrough into a new generation of machines." in 1963 Professor Donald B. Gillies discovered three Mersenne prime numbers while testing ILLIAC II, including the largest then known prime number, 2**11213 -1, which is over 3,000 digits.
The famous IBM System/360 (S/360) was first announced by IBM on April 7, 1964. S/360 became the most popular computer systems for more then a decade. It introduced 8-bit byte address space, byte addressing and many other things. The same year (1964) PL/1 was released. It became the most widely used programming language in Eastern Europe and the USSR. It later served as a prototype of several other languages including PL/M and C.
In 1964 the IBM 2311 Direct Access Storage Facility was introduced (History of IBM magnetic disk drives - Wikipedia,) for the System/360 series. It was also available on the IBM 1130 and (using the 2841 Control Unit) the IBM 1800. The 2311 mechanism was largely identical to the 1311, but recording improvements allowed higher data density. The 2311 stored 7.25 megabytes on a single removable IBM 1316 disk pack (the same type used on the IBM 1311) consisting of six platters that rotated as a single unit. Each recording surface had 200 tracks plus three optional tracks which could be used as alternatives in case faulty tracks were discovered. Average seek time was 85 ms. Data transfer rate was 156 kB/s.
Along with the development unified System 360 series of computers, IBM wanted a single programming language for all users. It hoped that Fortran could be extended to include the features needed by commercial programmers. In October 1963 a committee was formed composed originally of 3 IBMers from New York and 3 members of SHARE, the IBM scientific users group, to propose these extensions to Fortran. Given the constraints of Fortran, they were unable to do this and embarked on the design of a “new programming language” based loosely on Algol labeled “NPL". This acronym conflicted with that of the UK’s National Physical Laboratory and was replaced briefly by MPPL (MultiPurpose Programming Language) and, in 1965, with PL/I (with a Roman numeral “I” ). The first definition appeared in April 1964. IBM took NPL as a starting point and completed the design to a level that the first compiler could be written: the NPL definition was incomplete in scope and in detail. Control of the PL/I language was vested initially in the New York Programming Center and later at the IBM UK Laboratory at Hursley. The SHARE and GUIDE user groups were involved in extending the language and had a role in IBM’s process for controlling the language through their PL/I Projects. The language was first specified in detail in the manual “PL/I Language Specifications. C28-6571” written in New York from 1965 and superseded by “PL/I Language Specifications. GY33-6003” written in Hursley from 1967. IBM continued to develop PL/I in the late sixties and early seventies, publishing it in the GY33-6003 manual. These manuals were used by the Multics group and other early implementers. The first production PL/I compiler was the PL/I F compiler for the OS/360 Operating System, built by John Nash's team at Hursley in the UK: the runtime library team was managed by I.M.(Nobby) Clarke. Release 1 shipped in 1966. That was a significant step forward in comparison with earlier compilers. The PL/I D compiler, using 16 kilobytes of memory, was developed by IBM Germany for the DOS/360 low end operating system. It implemented a subset of the PL/I language requiring all strings and arrays to have fixed extents, thus simplifying the run-time environment. Reflecting the underlying operating system it lacked dynamic storage allocation and the controlled storage class. It was shipped within a year of PL/I F.
Hoare also invented Quicksort while on business trip to Moscow.
Douglas C. Englebart invents the computer mouse c. 1968, at SRI.
The first volume of The Art of Computer Programming was published in 1968 and instantly became classic Donald Knuth (b. 1938) later published two additional volumes of his world famous three-volume treatise
In 1968 ALGOL 68 , a monster language compared to ALGOL 60, appears. Some members of the specifications committee -- including C.A.R. Hoare and Niklaus Wirth -- protest its approval. ALGOL 68 proves difficult to implement. The same year Niklaus Wirth begins his work on a simple teaching language which later becomes Pascal.
Ted Hoff (b. 1937) and Federico Faggin at Intel designed the first microprocessor (computer on a chip) in 1969-1971.
In late 60th the PDP-11 one of the first 16-bit minicomputers was designed in a crash program by Harold McFarland, Gordon Bell, Roger Cady, and others as a response to NOVA 16-bit minicomputers. The project was able to leap forward in design with the arrival of Harold McFarland, who had been researching 16-bit designs at Carnegie Mellon University. One of his simpler designs became the PDP-11. It was launched in 1970 and became huge success. The first officially named version of Unix ran on the PDP-11/20 in 1970. It is commonly stated that the C programming language took advantage of several low-level PDP-11–dependent programming features, albeit not originally by design. A major advance in the PDP-11 design was Digital's Unibus, which supported all peripherals through memory mapping. This allowed a new device to be added easily, generally only requiring plugging a hardware interface board into the backplane, and then installing software that read and wrote to the mapped memory to control it. The relative ease of interfacing spawned a huge market of third party add-ons for the PDP-11, which made the machine even more useful. The combination of architectural innovations proved superior to competitors and the "11" architecture was soon the industry leader, propelling DEC back to a strong market position.
A second generation of programming languages, such as Basic, Algol 68 and Pascal (Designed by Niklaus Wirth in 1968-1969) appeared at the end of decade
Unix, a very influential operating system, was developed at Bell Laboratories by Ken Thompson (b. 1943) and Dennis Ritchie (b. 1941) after ATT withdraw from Multics project. Brian Kernighan and Ritchie together developed C, which became the most influential system programming language and also was used as general purpose language on personal computers. The first release was made in 1972. The definitive reference manual for it will not appear until 1974.
In early 1970th the PL/I Optimizer and Checkout compilers produced in Hursley supported a common level of PL/I language and aimed to replace the PL/I F compiler. The compilers had to produce identical results - the Checkout Compiler was used to debug programs that would then be submitted to the Optimizer. Given that the compilers had entirely different designs and were handling the full PL/I language this goal was challenging: it was achieved. The PL/I optimizing compiler took over from the PL/I F compiler and was IBM’s workhorse compiler from the 1970s to the 1990s. Like PL/I F, it was a multiple pass compiler with a 44kByte design point, but it was an entirely new design. Unlike the F compiler it had to perform compile time evaluation of constant expressions using the run-time library - reducing the maximum memory for a compiler phase to 28 kilobytes. A second-time around design, it succeeded in eliminating the annoyances of PL/I F such as cascading diagnostics. It was written in S/360 Macro Assembler by a team, led by Tony Burbridge, most of whom had worked on PL/I F. Macros were defined to automate common compiler services and to shield the compiler writers from the task of managing real-mode storage - allowing the compiler to be moved easily to other memory models. Program optimization techniques developed for the contemporary IBM Fortran H compiler were deployed: the Optimizer equaled Fortran execution speeds in the hands of good programmers. Announced with the IBM S/370 in 1970, it shipped first for the DOS/360 operating system in Aug 1971, and shortly afterward for OS/360, and the first virtual memory IBM operating systems OS/VS1, MVS and VM/CMS (the developers were unaware that while they were shoehorning the code into 28kB sections, IBM Poughkeepsie was finally ready to ship virtual memory support in OS/360). It supported the batch programming environments and, under TSO and CMS, it could be run interactively.
Simultaneously PL/C a dialect of PL/1 for education was developed at Cornell University in the early 1970s. It was designed with the specific goal of being used for teaching programming. The main authors were Richard W. Conway and Thomas R. Wilcox. They submitted the famous article "Design and implementation of a diagnostic compiler for PL/I" published in the Communications of ACM in March 1973. PL/C eliminated some of the more complex features of PL/I, and added extensive debugging and error recovery facilities. The PL/C compiler had the unusual capability of never failing to compile any program, through the use of extensive automatic correction of many syntax errors and by converting any remaining syntax errors to output statements.
In 1972 Gary Kildall implemented a subset of PL/1, called "PL/M" for microprocessors. PL/M was used to write the CP/M operating system - and much application software running on CP/M and MP/M. Digital Research also sold a PL/I compiler for the PC written in PL/M. PL/M was used to write much other software at Intel for the 8080, 8085, and Z-80 processors during the 1970s.
In 1973-74 Gary Kildall developed CP/M during , an operating system for an Intel Intellec-8 development system, equipped with a Shugart Associates 8-inch floppy disk drive interfaced via a custom floppy disk controller. It was written in PL/M. Various aspects of CP/M were influenced by the TOPS-10 operating system of the DECsystem-10 mainframe computer, which Kildall had used as a development environment.
The LSI-11 (PDP-11/03), introduced in February, 1975 was the first PDP-11 model produced using large-scale integration a precursor to personal PC.
The first RISC architecture was begun by John Cocke in 1975, at the Thomas J. Watson Laboratories of IBM. Similar projects started at Berkeley and Stanford around this time.
In March 1976 one of the first supercomputer CRAY-1 was shipped, designed by Seymour Cray (b. 1925) It could perform 160 million operations in a second. The Cray XMP came out in 1982. Later Cray Research was taken over by Silicon Graphics.
There were also major advances in algorithms and computational complexity. In 1971, Steve Cook published his seminal paper on NP-completeness, and shortly thereafter, Richard Karp showed that many natural combinatorial problems were NP-complete. Whit Diffie and Martin Hellman published a paper that introduced the theory of public-key cryptography, and a public-key cryptosystem known as RSA was invented by Ronald Rivest, Adi Shamir, and Leonard Adleman.
Microsoft was formed on April 4, 1975 to develop and sell BASIC interpreters for the Altair 8800. Bill Gates and Paul Allen write a version of BASIC that they sell to MITS (Micro Instrumentation and Telemetry Systems) on a per-copy royalty basis. MITS is producing the Altair, one of the earlier 8080-based microcomputers that came with a interpreter for a programming language.
The Apple I went on sale in July 1976 and was market-priced at $666.66 ($2,572 in 2011 dollars, adjusted for inflation.)
The Apple II was introduced on April 16, 1977 at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because it came with color graphics and an open architecture. While early models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a 5 1/4 inch floppy disk drive and interface, the Disk II.
In 1976, DEC decided to extend the PDP-11 architecture to 32-bits while adding a complete virtual memory system to the simple paging and memory protection of the PDP-11. The result was the VAX architecture. The first computer to use a VAX CPU was the VAX-11/780, which DEC referred to as a superminicomputer. Although it was not the first 32-bit minicomputer, the VAX-11/780's combination of features, price, and marketing almost immediately propelled it to a leadership position in the market after it was released in 1978. VAX systems were so successful that it propelled Unix to the status of major OS. in 1983, DEC canceled its Jupiter project, which had been intended to build a successor to the PDP-10 mainframe, and instead focused on promoting the VAX as the single computer architecture for the company.
In 1978 AWK -- a text-processing language named after the designers, Aho, Weinberger, and Kernighan -- appears. The same year the ANSI standard for FORTRAN 77 appears.
In 1977 Bill Joy, then a graduate student at Berkeley, started compiling the first Berkeley Software Distribution (1BSD), which was released on March 9, 1978
In 1979, three graduate students in North Carolina developed a distributed news server which eventually became Usenet.
The Second Berkeley Software Distribution (2BSD), was released in May 1979. It included updated versions of the 1BSD software as well as two new programs by Joy that persist on Unix systems to this day: the vi text editor (a visual version of ex) and the C shell.
The same 1979 VisiCalc the first spreadsheet program available for personal computers was conceived by Dan Bricklin, refined by Bob Frankston, developed by their company Software Arts, and distributed by Personal Software in 1979 (later named VisiCorp) for the Apple II computer
At the end of 1979 the kernel of BSD Unix was largely rewritten by Berkeley students to include a virtual memory implementation, and a complete operating system including the new kernel, ports of the 2BSD utilities to the VAX, was released as 3BSD at the end of 1979.
Microsoft purchased a license for Version 7 Unix from AT&T in 1979, and announced on August 25, 1980 that it would make it available for the 16-bit microcomputer market.
The success of 3BSD was a major factor in the Defense Advanced Research Projects Agency's (DARPA) decision to fund Berkeley's Computer Systems Research Group (CSRG), which would develop a standard Unix platform for future DARPA research in the VLSI Project and included TCP stack. CSRG released 4BSD, containing numerous improvements to the 3BSD system, in October 1980. 4BSD released in November 1980 offered a number of enhancements over 3BSD, notably job control in the previously released csh, delivermail (the antecedent of sendmail), "reliable" signals, and the Curses programming library.
This decade also saw the rise of the personal computer, thanks to Steve Wozniak and Steve Jobs, founders of Apple Computer.
In 1981 IBM PC was launched which made personal computer mainstream. The first computer viruses are developed also in 1981. The term was coined by Leonard Adleman, now at the University of Southern California. The same year, 1981, the first truly successful portable computer (predecessor of modern laptops) was marketed, the Osborne I.
In 1982 one of the first scripting languages REXX was released by IBM as a product. It was four years after AWK was released. Over the years IBM included REXX in almost all of its operating systems (VM/CMS, VM/GCS, MVS TSO/E, AS/400, VSE/ESA, AIX, CICS/ESA, PC DOS, and OS/2), and has made versions available for Novell NetWare, Windows, Java, and Linux.
In 1982 PostScript appears, which revolutionized printing on dot matrix and laser printers.
1983 was the year of major events in language area:
In 1984 Stallman published a rewritten version of Gosling's Emacs (GNU Emacs, where G stand for Goslings) as "free" software (Goslings sold the rights for his code to a commercial company), and launches the Free Software Foundation (FSF) to support the GNU project. One of the first program he decided to write is a C compiler that became widely knows as gcc. The same year Steven Levy "Hackers" book is published with a chapter devoted to RMS that presented him in an extremely favorable light.
In October 1983 Apple introduced the Macintosh computer which was the first GUI-based mass produced personal computer. It was three years after IBM PC was launched and six years after Apple II launch. It went of sale on Jan 24, 1984 two days after US$1.5 million Ridley Scott television commercial, "1984" was aired during Super Bowl XVIII on January 22, 1984. It is now considered a a "masterpiece.". In it an unnamed heroine to represent the coming of the Macintosh (indicated by a Picasso-style picture of Apple's Macintosh computer on her white tank top) as a means of saving humanity from the "conformity" of IBM's attempts to dominate the computer industry.
In 1985 Intel 80386 introduced 32-bit logical addressing. It became instrumental in Unix Renaissance which started the same year the launch of of Xenix 2.0 by Microsoft. It was based on UNIX System V. An update numbered 2.1.1 added support for the Intel 80286 processor. The Sperry PC/IT, an IBM PC AT clone, was advertised as capable of supporting eight simultaneous dumb terminal users under this version. Subsequent releases improved System V compatibility. The era of PC Unix started and Microsoft became dominant vendor of Unix: in the late 1980s, Xenix was, according to The Design and Implementation of the 4.3BSD UNIX Operating System, "probably the most widespread version of the UNIX operating system, according to the number of machines on which it runs". In 1987, SCO ported Xenix to the 386 processor. Microsoft used Xenix on Sun workstations and VAX minicomputers extensively within their company as late as 1992
Microsoft Excel was first released for Macintosh, not IBM PC, in 1985. The same year the combination of the Mac, Apple's LaserWriter printer, and Mac-specific software like Boston Software's MacPublisher and Aldus PageMaker enabled users to design, preview, and print page layouts complete with text and graphics—an activity to become known as desktop publishing.
The first version of GCC was able to compile itself in late 1985. The same year GNU Manifesto published
In 1986-1989 a series of computer viruses for PC DOS made headlines. One of the first mass viruses was boot virus called Brain created in 1986 by the Farooq Alvi Brothers in Lahore, Pakistan, reportedly to deter piracy of the software they had written.
In 1987, the US National Science Foundation started NSFnet, precursor to part of today's Internet.
The same year, 1987, Perl was released by Larry Wall. In 1988 Perl 2 was released.
Steve Jobs was ousted from Apple and formed his new company NeXT Computer with a dozen of former Apple employees. NeXT was the first affordable workstation with over megaflop computer power. It was in 1988, and the smaller NeXTstation in 1990. It was NeXTstation that was used to develop World Wide Web in CERN. It was also instrumental in creating of complex modern GUI interfaces and launching object oriented programming into mainstream...
In 1998 Human genome sequncing project started. A Brief History of the Human Genome Project
In 1988, Congress funded both the NIH and the DOE to embark on further exploration of this concept, and the two government agencies formalized an agreement by signing a Memorandum of Understanding to "coordinate research and technical activities related to the human genome."
James Watson was appointed to lead the NIH component, which was dubbed the Office of Human Genome Research. The following year, the Office of Human Genome Research evolved into the National Center for Human Genome Research (NCHGR).
In 1990, the initial planning stage was completed with the publication of a joint research plan, "Understanding Our Genetic Inheritance: The Human Genome Project, The First Five Years, FY 1991-1995." This initial research plan set out specific goals for the first five years of what was then projected to be a 15-year research effort.
In 1992, Watson resigned, and Michael Gottesman was appointed acting director of the center. The following year, Francis S. Collins was named director.
The advent and employment of improved research techniques, including the use of restriction fragment-length polymorphisms, the polymerase chain reaction, bacterial and yeast artificial chromosomes and pulsed-field gel electrophoresis, enabled rapid early progress. Therefore, the 1990 plan was updated with a new five-year plan announced in 1993 in the journal Science (262: 43-46; 1993).
1989 FSF introduces a General Public License (GPL). GPL is also known as 'copyleft'. Stallman redefines the word "free" in software to mean "GPL compatible". In 1990 As the president of the League for Programming Freedom (organization that fight software patterns), Stallman is given a $240,000 fellowship by the John D. and Catherine T. MacArthur Foundation.
4.3BSD-Reno came in early 1990. It was an interim release during the early development of 4.4BSD, and its use was considered a "gamble", hence the naming after the gambling center of Reno, Nevada. This release was explicitly moving towards POSIX compliance. Among the new features was an NFS implementation from the University of Guelph. In August 2006, Information Week magazine rated 4.3BSD as the "Greatest Software Ever Written".They commented: "BSD 4.3 represents the single biggest theoretical undergirder of the Internet."
On December 25 1990 the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet was accomplished in CERN. It was running on NeXT:
" Mike Sendall buys a NeXT cube for evaluation, and gives it to Tim [Berners-Lee]. Tim's prototype implementation on NeXTStep is made in the space of a few months, thanks to the qualities of the NeXTStep software development system. This prototype offers WYSIWYG browsing/authoring! Current Web browsers used in "surfing the Internet" are mere passive windows, depriving the user of the possibility to contribute. During some sessions in the CERN cafeteria, Tim and I try to find a catching name for the system. I was determined that the name should not yet again be taken from Greek mythology. Tim proposes "World-Wide Web". I like this very much, except that it is difficult to pronounce in French..." by Robert Cailliau, 2 November 1995.
In 1991 Linux was launched. The USSR was dissolved that led to influx of Russian programmers (as well as programmers from Eastern European countries) in the USA.
The first website was online on 6 August 1991:
"Info.cern.ch was the address of the world's first-ever web site and web server, running on a NeXT computer at CERN. The first web page address was http://info.cern.ch/hypertext/WWW/TheProject.html, which centred on information regarding the WWW project. Visitors could learn more about hypertext, technical details for creating their own webpage, and even an explanation on how to search the Web for information. There are no screenshots of this original page and, in any case, changes were made daily to the information available on the page as the WWW project developed. You may find a later copy (1992) on the World Wide Web Consortium website." -CERN
BSDi, the company formed to commercialized Unix BSD system found itself in legal trouble with AT&T's Unix System Laboratories (USL) subsidiary, then the owners of the System V copyright and the Unix trademark. The USL v. BSDi lawsuit was filed in 1992 and led to an injunction on the distribution of Net/2 until the validity of USL's copyright claims on the source could be determined. That launched Linux into mainstream.
FreeBSD development began in 1993 with a quickly growing, unofficial patchkit maintained by users of the 386BSD operating system. This patchkit forked from 386BSD and grew into an operating system taken from U.C. Berkeley's 4.3BSD-Lite (Net/2) tape with many 386BSD components and code from the Free Software Foundation.
On April 1993 CERN released the web technology into the public domain.
1994 First official Linux version 1.0 kernel released. Linux already has about 500,000 users. Unix renaissance started.
The same 1994 Microsoft incorporates Visual Basic for Applications into Excel, creating a way to knock out the competition of the Microsoft Office.
In February 1995, ISO accepts the 1995 revision of the Ada language. Called Ada 95, it includes OOP features and support for real-time systems.
In 1995 TCP connectivity in the USA became mainstream. Internet boom (aka dot-com boom) hit the USA. . Red Hat was formed by merger with ACC with Robert Yong of ACC (former founder of Linux Journal) a CEO.
In 1996 first computer monitoring system such as Tivoli and OpenView became established players.
In 1996 first ANSI C++ standard was released.
In 1997 Java was released. Also weak and primitive programming language if we consider its design (originally intended for imbedded systems), it proved to be durable and successful successor for Cobol. Sum Microsystems proved to be a capable marketing machine but that lead to deterioration of Solaris position and partial neglect of other projects such as Solaris on X86 and TCL. Microsoft launched a successful derivate of Java, called C# in December 2002.
In 1998 outsourcing that in 10 years destroy the USA programming industry became a fashion, fueleed by finacial industry attempts to exploit Internet boom for quick profits.
In 1999 a crazy connected with so called Millennium bug hit the USA. Proved lasting intellectual deterioration of some key US political figures including chairmen Greenspan --a cult like figure at the time.
In March 1999. Al Gore revealed that "During my service in the United States Congress, I took the initiative in creating the internet.". Which was partically true
This decade ended with 2000 dot-com boom bust. See Nikolai Bezroukov. Portraits of Open Source Pioneers. Ch 4: Grand Replicator aka Benevolent Dictator (A Slightly Skeptical View on Linus Torvalds)

I still have my HP 15C scientific calculator I bought in 1983 to get me through college for my engineering degree. There is nothing better than a hand held calculator that uses Reverse Polish Notation!
HP used to make fantastic products. I remember getting their RPN calculators back in th 80's; built like tanks.
Then they decided to "add value" by removing more and more material from their consumer/"prosumer" products until they became unspeakably flimsy. They stopped holding things together with proper fastenings and starting hot melting/gluing it together, so if it died you had to cut it open to have any chance of fixing it.
I still have one of their Laserjet 4100 printers. I expect it to outlast anything they currently produce, and it must be going on 16+ years old now.
Fuck you, HP. You started selling shit and now you're eating through your seed corn. I just wish the "leaders" who did this to you had to pay some kind of penalty greater than getting $25M in a severance package.

Also have a number of 42S calculators.....my day-to-day workhorse and several spares. I don't think the present HP could even dream of making these products today.

hey big brother.... if you are curious, there is a damn good android emulator of the HP42S available (Free42). really it is so good that it made me relax about accumulating more spares. still not quite the same as a real calculator. (the 42S, by the way, is the modernization/simplification of the classic HP41, the real hardcord very-programmable, reconfigurable, hackable unit with all the plug-in-modules that came out in the early 80s.)
Imagine working at HP and having to listen to Carly Fiorina bulldoze you...she is like a blow-torch...here are 4 minutes of Carly and Ralph Nader (if you can take it):
My husband has been a software architect for 30 years at the same company. Never before has he seen the sheer unadulterated panic in the executives. All indices are down and they are planning for the worst. Quality is being sacrificed for " just get some relatively functional piece of shit out the door we can sell". He is fighting because he has always produced a stellar product and refuses to have shit tied to his name ( 90% of competitor benchmarks fail against his projects). They can't afford to lay him off, but the first time in my life I see my husband want to quit...
I've been an engineer for 31 years - our managements's unspoken motto at the place I'm at (large company) is: "release it now, we'll put in the quality later". I try to put in as much as possible before the product is shoved out the door without killing myself doing it.
Do they even make test equipment anymore?
HP test and measurement was spun off many years ago as Agilent. The electronics part of Agilent was spun off as keysight late last year.
HP basically makes computer equipment (PCs, servers, Printers) and software. Part of the problem is that computer hardware has been commodized. Since PCs are cheap and frequent replacements are need, People just by the cheapest models, expecting to toss it in a couple of years and by a newer model (aka the Flat screen TV model). So there is no justification to use quality components. Same is become true with the Server market. Businesses have switched to virtualization and/or cloud systems. So instead of taking a boat load of time to rebuild a crashed server, the VM is just moved to another host.
HP has also adopted the Computer Associates business model (aka Borg). HP buys up new tech companies and sits on the tech and never improves it. It decays and gets replaced with a system from a competitor. It also has a habit of buying outdated tech companies that never generate the revenues HP thinks it will.
When Carly was CEO of HP, she instituted a draconian "pay for performance" plan. She ended up leaving with over $146 Million because she was smart enough not to specify "what type" of performance.
An era of leadership in computer technology has died, and there is no grave marker, not even a funeral ceremony or eulogy ... Hewlett-Packard, COMPAQ, Digital Equipment Corp, UNIVAC, Sperry-Rand, Data General, Tektronix, ZILOG, Advanced Micro Devices, Sun Microsystems, etc, etc, etc. So much change in so short a time, leaves your mind dizzy.

I returned to college several years ago after a 20 year hiatus (the first 6 years were my creative period). My first time around I studied what might be called pure Computer Science. A lot has happened in the industry after 20 years and I very much enjoyed conversations in class - esp with the perspective of the younger generation. I found it fascinating how many kids of today hoped to enter the gaming industry (my generation - Zork was popular when I was a kid and Myst was a breakout success on a new level). Kids today see blockbuster gaming as an almost make it rich experience - plus a "real world" job that sounds like fun.
But more interesting was the concepts of Computer Engineering vs Computer Science. What is Science vs Engineering? Are software "engineers" really scientists? Do they need to learn all this sciencey stuff in order to enter the business school? I attended a large semi-well-known University. Back in the '80s the CS department was "owned" by the school of business. Programming computers was thought to be the money maker - only business really used them with a strong overlap into engineering because computers were really big calculators. However it was a real CS curriculum with only 1 class for business majors. Fast forward a dozen years and CS is now part of the Engineering school (with Business on its own). The "kids" wondered why they needed to study Knuth et al when they were just going to be programming games. What about art? Story telling? They planned on using visual creative studio tools to create their works. Why all this science stuff? (this in a haptics class). Should a poet learn algorithms in order to operate MS-Word?
Since computers are ubiquitous they are used everywhere. I tell students to get a degree in what interests them - and learn how to use/program computers because...well..who doesn't use a computer? I used to program my TI calculator in highschool to pump out answers to physics & algebra questions (basic formulas).
Are those who program Excel Macros computer scientists? No. Computer Engineers? no. Business people solving real problems? Yes/maybe. The land is now wider. Many people don't care about the details of landing a man on the moon - but they like it when the velcro strap on their shoes holds properly. They receive entertainment via the Discovery Channel and get the dumbed down edition of all things "science."
When creating entertainment - it needs to be relatable to your target audience. The down and dirty details and technicalities interest only a few of us. My wife's eyes glaze over when I talk about some cool thing I'm working on. Retell it as saving the world and improving quality - she gets it (only to politely say I should go play with the kids -- but at least she was listening to that version of events).
I think that the dumbing down of history is ... well.. history. There was this thing called World War 2. The details I learned in grade school - lots of details. Each battle, names of important individuals. Today - lots of history has happened in the meantime. WW2 is now a bit dumbed down - still an important subject - but students still only have 8 grades in school with more material to cover.
My brain melts when I watch the Discovery Channel. I'm probably not the target audience. The details of historical science probably interest me. The history of Computing needs to be told like "The Social Network."

Donald Knuth Worried About the "Dumbing Down" of Computer Science History
Whether CS education is appropriate to all people who do computed-assisted technical work is very irrelevant to me since practical forces in real life simply solve that issue.
The problem I care about is a problem I seen in CS for real. I've met quite a few CS grads who don't know who Knuth, Lamport, Liskov, Hoare Tarjan, o Dijkstra are.
If you (the generic CS grad) do not know who they are, how the hell do you know about basic CS things like routing algorithms, pre and post conditions, data structures, you know, the very basic shit that is supposed to be the bread and butter of CS????
It is ok not to know these things and these people if you are a Computer Engineer, MIS or Network/Telecomm engineer (to a degree dependent on what your job expects from you.)
But if you are Computer Scientist, my God, this is like hiring an Electrical Engineer who doesn't know who Maxwell was. It does not inspire a lot of confidence, does it?

Re:Don't do what they did to math (Score:1)
Knuth did a nice job of articulating why he wants to look at the history of things at the beginning of the video. Those reasons might not resonate with you but he does have definite reasons for wanting technical histories (not social histories which pander to "the stupid") to be written.
Dec 26, 2014 | Communications of the ACM, January 2015
In his lecture Knuth worried that a "dismal trend" in historical work meant that "all we get nowadays is dumbed down" through the elimination of technical detail. According to Knuth "historians of math have always faced the fact that they won't be able to please everybody." He feels that other historians of science have succumbed to "the delusion that ... an ordinary person can understand physics ..."
I am going to tell you why Knuth's tears were misguided, or at least misdirected, but first let me stress that historians of computing deeply appreciate his conviction that our mission is of profound importance. Indeed, one distinguished historian of computing recently asked me what he could do to get flamed by Knuth. Knuth has been engaged for decades with history. This is not one of his passionate interests outside computer science, such as his project reading verses 3:16 of different books of the Bible. Knuth's core work on computer programming reflects a historical sensibility, as he tracks down the origin and development of algorithms and reconstructs the development of thought in specific areas. For years advertisements for IEEE Annals of the History of Computing, where Campbell-Kelly's paper was published, relied on a quote from Knuth that it was the only publication he read from cover to cover. With the freedom to choose a vital topic for a distinguished lecture Knuth chose to focus on history rather than one of his better-known scientific enthusiasms such as literate programming or his progress with The Art of Computer Programming.
... Distinguished computer scientists are prone to blur their own discipline, and in particular few dozen elite programs, with the much broader field of computing. The tools and ideas produced by computer scientists underpin all areas of IT and make possible the work carried out by network technicians, business analysts, help desk workers, and Excel programmers. That does not make those workers computer scientists. The U.S. alone is estimated to have more than 10 million "information technology workers," which is about a hundred times more than the ACM's membership. Vint Cerf has warned in Communications that even the population of "professional programmers" dwarfs the association's membership.7 ACM's share of the IT workforce has been in decline for a half-century, despite efforts begun back in the 1960s and 1970s by leaders such as Walter Carlson and Herb Grosch to broaden its appeal.
... ... ...
So why is the history of computer science not being written in the volume it deserves, or the manner favored by Knuth? I am, at heart, a social historian of science and technology and so my analysis of the situation is grounded in disciplinary and institutional factors. Books of this kind would demand years of expert research and sell a few hundred copies. They would thus be authored by those not expected to support themselves with royalties, primarily academics.
... ... ...
The history of science is a kind of history, which is in turn part of the humanities. Some historians of science are specialists within broad history departments, and others work in specialized programs devoted to science studies or to the history of science, technology, or medicine. In both settings, historians judge the work of prospective colleagues by the standards of history, not those of computer science. There are no faculty jobs earmarked for scholars with doctoral training in the history of computing, still less in the history of computer science. The persistently brutal state of the humanities job market means that search committees can shortlist candidates precisely fitting whatever obscure combination of geographical area, time period, and methodological approaches are desired. So a bright young scholar aspiring to a career teaching and researching the history of computer science would need to appear to a humanities search committee as an exceptionally well qualified historian of the variety being sought (perhaps a specialist in gender studies or the history of capitalism) who happens to work on topics related to computing.
... ... ...
Thus the kind of historical work Knuth would like to read would have to be written by computer scientists themselves. Some disciplines support careers spent teaching history to their students and writing history for their practitioners. Knuth himself holds up the history of mathematics as an example of what the history of computing should be. It is possible to earn a Ph.D. within some mathematics departments by writing a historical thesis (euphemistically referred to as an "expository" approach). Such departments have also been known to hire, tenure, and promote scholars whose research is primarily historical. Likewise medical schools, law schools, and a few business schools have hired and trained historians. A friend involved in a history of medicine program recently told me that its Ph.D. students are helped to shape their work and market themselves differently depending on whether they are seeking jobs in medical schools or in history programs. In other words, some medical schools and mathematics departments have created a demand for scholars working on the history of their disciplines and in response a supply of such scholars has arisen.
As Knuth himself noted toward the end of his talk, computer science does not offer such possibilities. As far as I am aware no computer science department in the U.S. has ever hired as a faculty member someone who wrote a Ph.D. on a historical topic within computer science, still less someone with a Ph.D. in history. I am also not aware of anyone in the U.S. having been tenured or promoted within a computer science department on the basis of work on the history of computer science. Campbell-Kelly, now retired, did both things (earning his Ph.D. in computer science under Randell's direction) but he worked in England where reputable computer science departments have been more open to "fuzzy" topics than their American counterparts. Neither are the review processes and presentation formats at prestigious computer conferences well suited for the presentation of historical work. Nobody can reasonably expect to build a career within computer science by researching its history.
In its early days the history of computing was studied primarily by those who had already made their careers and could afford to indulge pursuing historical interests from tenured positions or to dabble after retirement. Despite some worthy initiatives, such as the efforts of the ACM History Committee to encourage historical projects, the impulse to write technical history has not spread widely among younger generations of distinguished and secure computer scientists.
... ... ...
Contrary both to Knuth's despair and to Campbell-Kelly's story of a march of progress away from technical history, some scholars with formal training in history and philosophy have been turning to topics with more direct connections to computer science over the past few years. Liesbeth De Mol and Maarten Bullynck have been working to engage the history and philosophy of mathematics with issues raised by early computing practice and to bring computer scientists into more contact with historical work.3 Working with like-minded colleagues, they helped to establish a new Commission for the History and Philosophy of Computing within the International Union of the History and Philosophy of Science. Edgar Daylight has been interviewing famous computer scientists, Knuth included, and weaving their remarks into fragments of a broader history of computer science.8 Matti Tedre has been working on the historical shaping of computer science and its development as a discipline.22 The history of Algol was a major focus of the recent European Science Foundation project Software for Europe. Algol, as its developers themselves have observed, was important not only for pioneering new capabilities such as recursive functions and block structures, but as a project bringing together a number of brilliant research-minded systems programmers from different countries at a time when computer science had yet to coalesce as a discipline.c Pierre Mounier-Kuhn has looked deeply into the institutional history of computer science in France and its relationship to the development of the computer industry.16
Stephanie Dick, who recently earned her Ph.D. from Harvard, has been exploring the history of artificial intelligence with close attention to technical aspects such as the development and significance of the linked list data structure.d Rebecca Slayton, another Harvard Ph.D., has written about the engagement of prominent computer scientists with the debate on the feasibility of the "Star Wars" missile defense system; her thesis has been published as an MIT Press book.20 At Princeton, Ksenia Tatarchenko recently completed a dissertation on the USSR's flagship Akademgorodok Computer Center and its relationship to Western computer science.21 British researcher Mark Priestley has written a deep and careful exploration of the history of computer architecture and its relationship to ideas about computation and logic.18 I have worked with Priestly to explore the history of ENIAC, looking in great detail at the functioning and development of what we believe to be the first modern computer program ever executed.9 Our research engaged with some of the earliest historical work on computing, including Knuth's own examination of John von Neumann's first sketch of a modern computer program10 and Campbell-Kelly's technical papers on early programming techniques.5

Obituary Former IBM CEO John Akers has died in Boston aged 79.
Big Blue announced Akers' passing here, due to a stroke according to Bloomberg.After a stint as a US Navy pilot, the IBM obit states, Akers joined the company in 1960. His 33-year stint with IBM culminated in his appointment as its sixth CEO in 1985, following three years as president.
The top job became something of a poisoned chalice for Akers: the IBM PC project was green-lit during his tenure, and the industry spawned by this computer would cannibalize Big Blue's mainframe revenue, which was already under attack from minicomputers.
His career was founded on the success of the iconic System/360 and System/370 iron, but eventually fell victim to one of the first big disruptions the industry experienced.
He was eventually replaced by Lou Gerstner (as Bloomberg notes, the first CEO to be appointed from outside IBM).
To Gerstner fell the task of reversing the losses IBM was racking up – US$7.8 billion over two years – by embarking on a top-down restructure to shave US$7 billion in costs.
According to retired IBM executive Nicholas Donofrio, Akers took a strong interest in nursing the behind-schedule RS6000 Unix workstation project through to fruition in the late 1980s:
“he asked what additional resources I needed and agreed to meet with me monthly to ensure we made the new schedule”.
Apr 08, 2014 | The Register
IBM's System 360 mainframe, celebrating its 50th anniversary on Monday, was more than a just another computer. The S/360 changed IBM just as it changed computing and the technology industry.
The digital computers that were to become known as mainframes were already being sold by companies during the 1950s and 1960s - so the S/360 wasn't a first.
Where the S/360 was different was that it introduced a brand-new way of thinking about how computers could and should be built and used.
The S/360 made computing affordable and practical - relatively speaking. We're not talking the personal computer revolution of the 1980s, but it was a step.
The secret was a modern system: a new architecture and design that allowed the manufacturer - IBM - to churn out S/360s at relatively low cost. This had the more important effect of turning mainframes into a scalable and profitable business for IBM, thereby creating a mass market.
The S/360 democratized computing, taking it out of the hands of government and universities and putting its power in the hands of many ordinary businesses.
The birth of IBM's mainframe was made all the more remarkable given making the machine required not just a new way of thinking but a new way of manufacturing. The S/360 produced a corporate and a mental restructuring of IBM, turning it into the computing giant we have today.
The S/360 also introduced new technologies, such as IBM's Solid Logic Technology (SLT) in 1964 that meant a faster and a much smaller machine than what was coming from the competition of the time.
Big Blue introduced new concepts and de facto standards with us now: virtualisation - the toast of cloud computing on the PC and distributed x86 server that succeeded the mainframe - and the 8-bit byte over the 6-bit byte.
The S/360 helped IBM see off a rising tide of competitors such that by the 1970s, rivals were dismissively known as "the BUNCH" or the dwarves. Success was a mixed blessing for IBM, which got in trouble with US regulators for being "too" successful and spent a decade fighting a government anti-trust law suit over the mainframe business.
The legacy of the S/360 is with us today, outside of IBM and the technology sector.
S/360 I knew you well
The S/390 name is a hint to its lineage, S/360 -> S/370 -> S/390, I'm not sure what happened to the S/380. Having made a huge jump with S/360 they tried to do the same thing in the 1970s with the Future Systems project, this turned out to be a huge flop, lots of money spent on creating new ideas that would leapfrog the competition, but ultimately failed. Some of the ideas emerged on the System/38 and onto the original AS/400s, like having a query-able database for the file system rather than what we are used to now.
The link to NASA with the S/360 is explicit with JES2 (Job Execution Subsystem 2) the element of the OS that controls batch jobs and the like. Messages from JES2 start with the prefix HASP, which stands for Houston Automatic Spooling Program.
As a side note, CICS is developed at Hursley Park in Hampshire. It wasn't started there though. CICS system messages start with DFH which allegedly stands for Denver Foot Hills. A hint to its physical origins, IBM swapped the development sites for CICS and PL/1 long ago.
I've not touched an IBM mainframe for nearly twenty years, and it worries me that I have this information still in my head. I need to lie down!
Re: S/360 I knew you well
I have great memories of being a Computer Operator on a 360/40. They were amazing capable and interesting machines (and peripherals).
Re: S/360 I knew you well
ESA is the bit that you are missing - the whole extended address thing, data spaces,hyperspaces and cross-memory extensions.
Fantastic machines though - I learned everything I know about computing from Principals of Operations and the source code for VM/SP - they used to ship you all that, and send you the listings for everything else on microfiche. I almost feel sorry for the younger generations that they will never see a proper machine room with the ECL water-cooled monsters and attendant farms of DASD and tape drives. After the 9750's came along they sort of look like very groovy American fridge-freezers.
Mind you, I can get better mippage on my Thinkpad with Hercules than the 3090 I worked with back in the 80's, but I couldn't run a UK-wide distribution system, with thousands of concurrent users, on it.
Nice article, BTW, and an upvote for the post mentioning The Mythical Man Month; utterly and reliably true.
Happy birthday IBM Mainframe, and thanks for keeping me in gainful employment and beer for 30 years!
Re: S/360 I knew you well
I stated programming (IBM 360 67) and have programmed several IBM mainframe computers. One of the reason for the ability to handle large amounts of data is that these machines communicate to terminals in EBCDIC characters, which is similar to ASCII. It took very few of these characters to program the 3270 display terminals, while modern X86 computers use a graphical display and need a lot data transmitted to paint a screen. I worked for a company that had an IBM-370-168 with VM running both os and VMS.
We had over 1500 terminals connected to this mainframe over 4 states. IBM had visioned that VM/CMS. CICS was only supposed to be a temporary solution to handling display terminals, but it became the main stay in many shops.
Our shop had over 50 3330 300 meg disk drives online with at least 15 tape units. These machines are in use today, in part, because the cost of converting to X86 is prohibitive.
On these old 370 CICS, the screens were separate from the program. JCL (job control language) was used to initiate jobs, but unlike modern batch files, it would attach resources such as a hard drive or tape to the program. This is totally foreign to any modern OS.
Linux or Unix can come close but MS products are totally different.
Re: S/360 I knew you well
S/380 was the "future systems program" that was cut down to the S/38 mini.
HASP was the original "grid scheduler" in Houston running on a dedicated mainframe scheduling work to the other 23 mainframes under the bridge.. I nearly wet myself with laughter reading Data-Synapse documentation and their "invention" of a job-control-language. 40 years ago HASP was doing Map/Reduce to process data faster than a tape-drive could handle.
If we don't learn the lessons of history, we are destined to IEFBR14!
Come and look at this!
As a senior IT bod said to me one time, when I was doing some work for a mobile phone outfit.
"it's an IBM engineer getting his hands dirty".
And so it was: a hardware guy, with his sleeves rolled up and blood grime on his hands, replacing a failed board in an IBM mainframe.
The reason it was so noteworthy, even in the early 90's was because it was such a rare occurrence. It was probably one of the major selling points of IBM computers (the other one, with just as much traction, is the ability to do a fork-lift upgrade in a weekend and know it will work.) that they didn't blow a gasket if you looked at them wrong.
The reliability and compatibility across ranges is why people choose this kit. It may be arcane, old-fashioned, expensive and untrendy - but it keeps on running.
The other major legacy of OS/360 was, of course, The Mythical Man Month who's readership is still the most reliable way of telling the professional IT managers from the wannabees who only have buzzwords as a knowledge base.
Re: Come and look at this!
They were bloody good guys from IBM!
I started off working on mainframes around 1989, as graveyard shift "tape monkey" loading tapes for batch jobs. My first solo job was as a Unix admin on a set of RS/6000 boxes, I once blew out the firmware and a test box wouldn't boot.
I called out an IBM engineer after I completely "futzed" the box, he came out and spent about 2 hours with me teaching me how to select and load the correct firmware. He then spent another 30 mins checking my production system with me and even left me his phone number so I call him directly if I needed help when I did the production box.
I did the prod box with no issues because of the confidence I got and the time he spent with me. Cheers!
Re: 16 bit byte?
The typo must be fixed, the article says 6-bit now. The following is for those who have no idea what we are talking about.
Generally machines prior to the S/360 were 6-bit if character or 36-bit if word oriented. The S/360 was the first IBM architecture (thank you Dr's Brooks, Blaauw and Amdahl) to provide both data types with appropriate instructions and to include a "full" character set (256 characters instead of 64) and to provide a concise decimal format (2 digits in one character position instead of 1) 8-bits was chosen as the "character" length.
It did mean a lot of Fortran code had to be reworked to deal with 32-bit single precision or 32 bit integers instead of the previous 36-bit.
If you think the old ways are gone, have a look at the data formats for the Unisys 2200.
Came with the S/370, not the S/360, which didn't even have virtual memory.
The 360/168 had it, but it was a rare beast.
Nope. CP/67 was the forerunner of IBM's VM. Ran on S/360
S/360 Model 67 running CP67 (CMS which became VM) or the Michigan Terminal System. The Model 67 was a Model 65 with a DAT box to support paging/segmentation but CP67 only ever supported paging (I think, it's been a few years).
The 360/168 had a proper MMU and thus supported virtual memory. I interviewed at Bradford university, where they had a 360/168 that they were doing all sorts of things that IBM hadn't contemplated with (like using conventional glass teletypes hooked to minicomputers so they could emulate the page based - and more expensive - IBM terminals).
I didn't get to use an IBM mainframe in anger until the 3090/600 was available (where DEC told the company that they'd need a 96 VAX cluster and IBM said that one 3090/600J would do the same task). At the time we were using VM/TSO and SQL/DS, and were hitting 16MB memory size limits.
Re: Virtualisation @Steve Todd
I'm not sure that the 360/168 was a real model. The Wikipedia article does not think so either.
As far as I recall, the only /168 model was the 370/168, one of which was at Newcastle University in the UK, serving other Universities in the north-east of the UK, including Durham (where I was) and Edinburgh.
They also still had a 360/65, and one of the exercises we had to do was write some JCL in OS/360. The 370 ran MTS rather than an IBM OS.
You're right. The 360/67 was the first VM - I had the privilege of trying it out a few times. It was a bit slow though. The first version of CP/67 only supported 2 terminals I recall... The VM capability was impressive. You could treat files as though they were in real memory - no explicit I/O necessary.
This was a big factor in the profitability of mainframes. There was no such thing as an 'industry-standard' interface - either physical or logical. If you needed to replace a memory module or disk drive, you had no option* but to buy a new one from IBM and pay one of their engineers to install it (and your system would probably be 'down' for as long as this operation took). So nearly everyone took out a maintenance contract, which could easily run to an annual 10-20% of the list price. Purchase prices could be heavily discounted (depending on how desperate your salesperson was) - maintenance charges almost never were.
* There actually were a few IBM 'plug-compatible' manufacturers - Amdahl and Fujitsu. But even then you couldn't mix and match components - you could only buy a complete system from Amdahl, and then pay their maintenance charges. And since IBM had total control over the interface specs and could change them at will in new models, PCMs were generally playing catch-up.
So true re the service costs, but "Field Engineering" as a profit centre and a big one at that. Not true regarding having to buy "complete" systems for compatibility. In the 70's I had a room full of CDC disks on a Model 40 bought because they were cheaper and had a faster linear motor positioner (the thing that moved the heads), while the real 2311's used hydraulic positioners. Bad day when there was a puddle of oil under the 2311.

Back in the day one of the Scheduler software suppliers made a shed load of money (the SW was $250k a pop) by making new jobs start a lot faster and letting shops put back their memory upgrades by a year or two.
Mainframe memory was expensive.
Now owned by CA (along with many things mainframe) and so probably gone to s**t.
Done with some frequency. In the DoD agency where I worked we had mostly Memorex disks as I remember it, along with various non-IBM as well as IBM tape drives, and later got an STK tape library. Occasionally there were reports of problems where the different manufacturers' CEs would try to shift blame before getting down to the fix.
I particularly remember rooting around in a Syncsort core dump that ran to a couple of cubic feet from a problem eventually tracked down to firmware in a Memorex controller. This highlighted the enormous I/O capacity of these systems, something that seems to have been overlooked in the article. The dump showed mainly long sequences of chained channel programs that allowed the mainframe to transfer huge amounts of data by executing a single instruction to the channel processors, and perform other possibly useful work while awaiting completion of the asynchronous I/O.
@ChrisMiller - The IBM I/O channel was so well-specified that it was pretty much a standard. Look at what the Systems Concepts guys did - a Dec10 I/O and memory bus to IBM channel converter. Had one of those in the Imperial HENP group so we could use IBM 6250bpi drives as DEC were late to market with them. And the DEC 1600 bpi drives were horribly unreliable.
The IBM drives were awesome. It was always amusing explaining to IBM techs why they couldn't run online diags. On the rare occasions when they needed fixing.
It all comes flooding back.
A long CCW chain, some of which are the equivalent of NOP in channel talk (where did I put that green card?) with a TIC (Transfer in Channel, think branch) at the bottom of the chain back to the top. The idea was to take an interrupt (PCI) on some CCW in the chain and get back to convert the NOPs to real CCWs to continue the chain without ending it. Certainly the way the page pool was handled in CP67.
And I too remember the dumps coming on trollies. There was software to analyse a dump tape but that name is now long gone (as was the origin of most of the problems in the dumps). Those were the days I could not just add and subtract in hex but multiply as well.
The Mythical Man-Month
Fred Brooks' seminal work on the management of large software projects, was written after he managed the design of OS/360. If you can get around the mentions of secretaries, typed meeting notes and keypunches, it's required reading for anyone who manages a software project. Come to think of it...*any* engineering project. I've recommended it to several people and been thanked for it.
// Real Computers have switches and lights...
The Mythical Man-Month
The key concepts of this book are as relevant today as they were back in the 60s and 70s - it is still oft quoted ("there are no silver bullets" being one I've heard recently). Unfortunately fewer and fewer people have heard of this book these days and even fewer have read it, even in project management circles.
Was IBM ever cheaper?
I've been in IT since the 1970s.
My understanding from the guys who were old timers when I started was the big thing with the 360 was the standardized Op Codes that would remain the same from model to model, with enhancements, but never would an Op Code be withdrawn.
The beauty of IBM s/360 and s/370 was you had model independence. The promise was made, and the promise was kept, that after re-writing your programs in BAL (360's Basic Assembler Language) you'd never have to re-code your assembler programs ever again.
Also the re-locating loader and method of link editing meant you didn't have to re-assemble programs to run them on a different computer. Either they would simply run as it, or they would run after being re-linked. (When I started, linking might take 5 minutes, where re-assembling might take 4 hours, for one program. I seem to recall talk of assemblies taking all day in the 1960s.)
I wasn't there in the 1950s and 60s, but I don't recall any one ever boasting at how 360s or 370s were cheaper than competitors.
IBM products were always the most expensive, easily the most expensive, at least in Canada.
But maybe in the UK it was like that. After all the UK had its own native computer manufacturers that IBM had to squeeze out despite patriotism still being a thing in business at the time.
Cut my programming teeth on S/390 TSO architecture
We were developing CAD/CAM programs in this environment starting in the early eighties, because it's what was available then, based on use of this system for stock control in a large electronics manufacturing environment. We fairly soon moved this Fortran code onto smaller machines, DEC/VAX minicomputers and early Apollo workstations. We even had an early IBM-PC in the development lab, but this was more a curiosity than something we could do much real work on initially. The Unix based Apollo and early Sun workstations were much closer to later PCs once these acquired similar amounts of memory, X-Windows like GUIs and more respectable graphics and storage capabilities, and multi-user operating systems.
Ahh S/360 I knew thee well
Cut my programming teeth on OS/390 assembler (TPF) at Galileo - one of Amadeus' competitors.
I interviewed for Amadeus's initial project for moving off of S/390 in 1999 and it had been planned for at least a year or 2 before that - now that was a long term project!
Re: Ahh S/360 I knew thee well
There are people who worked on Galileo still alive? And ACP/TPF still lives, as zTPF? I remember a headhunter chasing me in the early 80's for a job in OZ, Quantas looking for ACP/TPF coders, $80k US, very temping.
You can do everything in 2k segments of BAL.
No mention of microcode?
Unless I missed it, there was no reference to microcode which was specific to each individual model of the S/360 and S/370 ranges, at least, and provided the 'common interface' for IBM Assembler op-codes. It is the rough equivalent of PC firmware. It was documented in thick A3 black folders held in two-layer trolleys (most of which held circuit diagrams, and other engineering amusements), and was interesting to read (if not understand). There you could see that the IBM Assembler op-codes each translated into tens or hundreds of microcode machine instructions. Even 0700, NO-OP, got expanded into surprisingly many machine instructions.

Re: No mention of microcode?
"I first met microcode by writing a routine to do addition for my company's s/370. Oddly, they wouldn't let me try it out on the production system :-)"
I did not know the microcode store was writeable.
Microcode was a core (no pun intended) feature of the S/360/370/390/4030/z architecture.
It allowed IBM to trade actual hardware (EG a full spec hardware multiplier) for partial (part word or single word) or completely software based (microcode loop) depending on the machines spec (and the customers pocket) without needing a re compile as at the assembler level it would be the same instruction.
I'd guess hacking the microcode would call for exceptional bravery on a production machine.
Arnaut the less
Re: No mention of microcode? - floppy disk
Someone will doubtless correct me, but as I understood it the floppy was invented as a way of loading the microcode into the mainframe CPU.
The rule of thumb in use (from Brooks's Mythical Man Month, as I remember) is around 5 debugged lines of code per programmer per day, pretty much irrespective of the language. And although the end code might have been a million lines, some of it probably needed to be written several times: another memorable Brooks item about large programming projects is "plan to throw one away, because you will."
Programming systems product
The main reason for what appears, at first sight, low productivity is spelled out in "The Mythical Man-Month". Brooks freely concedes that anyone who has just learned to program would expect to be many times more productive than his huge crew of seasoned professionals. Then he explains, with the aid of a diagram divided into four quadrants.
Top left, we have the simple program. When a program gets big and complex enough, it becomes a programming system, which takes a team to write it rather than a single individual. And that introduces many extra time-consuming aspects and much overhead.
Going the other way, writing a simple program is far easier than creating a product with software at its core. Something that will be sold as a commercial product must be tested seven ways from Sunday, made as maintainable and extensible as possible, be supplemented with manuals, training courses, and technical support services, etc.
Finally, put the two together and you get the programming systems product, which can be 100 times more expensive and time-consuming to create than an equivalent simple program.
"Why won't you DIE?"
I suppose that witty, but utterly inappropriate, heading was added by an editor; Gavin knows better.
If anyone is in doubt, the answer would be the same as for other elderly technology such as houses, roads, clothing, cars, aeroplanes, radio, TV, etc. Namely, it works - and after 50 years of widespread practical use, it has been refined so that it now works *bloody well*. In extreme contrast to many more recent examples of computing innovation, I may add.
Whoever added that ill-advised attempt at humour should be forced to write out 1,000 times:
"The definition of a legacy system: ONE THAT WORKS".
Re: Pay Per Line Of Code
I worked for IBM UK in the 60s and wrote a lot of code for many different customers. There was never a charge. It was all part of the built in customer support. I even rewrote part of the OS for one system (not s/360 - IBM 1710 I think) for Rolls Royce aero engines to allow all the user code for monitoring engine test cells to fit in memory.
Sole Source For Hardware?
Even before the advent of Plug Compatible Machines brought competition for the Central Processing Units, the S/360 peripheral hardware market was open to third parties. IBM published the technical specifications for the bus and tag channel interfaces allowing, indeed, encouraging vendors to produce plug and play devices for the architecture, even in competition with IBM's own. My first S/360 in 1972 had Marshall not IBM disks and a Calcomp drum plotter for which IBM offered no counterpart. This was true of the IBM Personal Computer as well. This type of openness dramatically expands the marketability of a new platform architecture.
Eventually we stripped scrapped 360s for components.
"IBM built its own circuits for S/360, Solid Logic Technology (SLT) - a set of transistors and diodes mounted on a circuit twenty-eight-thousandths of a square inch and protected by a film of glass just sixty-millionths of an inch thick. The SLT was 10 times more dense the technology of its day."
When these machines were eventually scrapped we used the components from them for electronic projects. Their unusual construction was a pain, much of the 'componentry' couldn't be used because of the construction. (That was further compounded by IBM actually partially smashing modules before they were released as scrap.)
"p3 [Photo caption] The S/360 Model 91 at NASA's Goddard Space Flight Center, with 2,097,152 bytes of main memory, was announced in 1968"
Around that time our 360 only had 44kB memory, it was later expanded to 77kB in about 1969. Why those odd values were chosen is still somewhat a mystery to me.
Re: Eventually we stripped scrapped 360s for components.
@RobHib-The odd memory was probably the size of the memory available for the user, not the hardware size (which came in powers of 2 multiples). The size the OS took was a function of what devices were attached and a few other sysgen parameters. Whatever was left after the OS was user space. There was usually a 2k boundary since memory protect keys worked on 2k chunks, but not always, some customers ran naked to squeeze out those extra bytes.

Primacy of software
Could have had a little more about the primacy of software: IBM had a huge range of compliers, and having an assembling language common across a wide range was a huge winner (as obvious as that seems today in an age of a handful of processor instruction sets). Furthermore, IBM had a strong focus on binary compatibility, and the lack of that with some competitor's ranges made shipping software for those machines much more expensive than for IBM.
IBM also sustained that commitment to development. Which meant that until the minicomputer age they were really the only possibility if you wanted newer features (such as CICS for screen-based transaction processing or VSAM or DB2 for databases, or VMs for a cheaper test versus production environment). Other manufacturers would develop against their forthcoming models, not their shipped models, and so IBM would be the company "shipping now" with the feature you desired.
IBM were also very focused on business. They knew how to market (eg, the myth of 'idle' versus 'ready' light on tape drives, whitepapers to explain technology to managers). They knew how to charge (eg, essentially a lease, which matched company's revenue). They knew how to do politics (eg, lobbying the Australian PM after they lost a government sale). They knew how to do support (with their customer engineers basically being a little bit of IBM embedded at the customer). Their strategic planning is still world class.
I would be cautious about lauding the $0.5B taken to develop the OS/360 software as progress. As a counterpoint consider Burroughs, who delivered better capability with less lines of code, since they wrote in Algol rather than assembler. Both companies got one thing right: huge libraries of code which made life much easier for applications programmers.
DEC's VMS learnt that lesson well. It wasn't until MS-DOS that we were suddenly dropped back into an inferior programming environment (but you'll cope with a lot for sheer responsiveness, and it didn't take too long until you could buy in what you needed).
What killed the mainframe was its sheer optimisation for batch and transaction processing and the massive cost if you used it any other way. Consider that TCP/IP used about 3% of the system's resources, or $30k pa of mainframe time. That would pay for a new Unix machine every year to host your website on.

The biggest concern seems to be distraction. Google Glass looks like a pair of glasses, minus the lenses; it's just a band across your forehead, with a tiny screen mounted at the upper-right side. By tapping the earpiece and using spoken commands, you direct it to do smartphone-ish tasks, such as fielding a calendar alert and finding a nearby sushi restaurant.
Just what we need, right? People reading texts and watching movies while they drive and attaining new heights of rudeness by scanning their e-mail during face-to-face conversation.
Those are misguided concerns. When I finally got to try Google Glass, I realized that they don't put anything in front of your eyes. You still make eye contact when you talk. You still see the road ahead. The screen is so tiny, it doesn't block your normal vision.
Hilarious parody videos show people undergoing all kinds of injury while peering at the world through a screen cluttered with alerts and ads. But that's not quite how it works. You glance up now and then, exactly as you would check your phone. But because you don't have to look down and dig around in your pocket, you could argue that there's less distraction. By being so hands-free, it should be incredibly handy.

Although the fallibility of the human monkey is much trumpeted (e.g. "To Err is Human", NAS study of out of control corporate iatrogenic death in America), there is one area of human activity where we score an almost 100% reliability: the 'justifiability' of the sport shooting of the mentally ill, Big Pharma crazed, suicidal, or just simply angry folks amongst us by our local and national 'law enforcement' (LE). Well, not all are simply shooting for sport, many are the result of overwhelming panic (e.g. 17 or 57 bullet holes in the human target) of individuals who shouldn't be allowed to own a sharp pencil much less carry a gun with a license to kill. I have not bothered to look for the statistics presuming them to be either not available or obfuscated in some way but rely on my local newspaper for my almost daily story of a local police shooting.
With that said, one can only say YES! to Google Glass and its most obvious use, replacing the patrol car dash cam. Every uniformed 'law enforcement' officer and 'security guard' must be so equipped and required to have the camera on and recording at any time on 'duty' and not doing duty in the can or on some other 'personal' time. Consider it simply as having one's supervisor as a 'partner'. Same rules would apply. No sweat.

It really is a great idea.
A pair of glasses that can project information or perform actions on a virtual screen in front of you about pretty much anything and all you have to do is ask. Driving directions. LinkedIn LNKD -0.59% connections. Order history. A photo. A video. A phone call. An email. The options seem limitless. And they are. Google GOOG -0.37% Glass really is a great idea. The technology can and probably will change the world. So how did Google screw it up?
Yes, screw it up. Since first announcing the product in 2012, Google Glass has been subject to ridicule and even violence. It’s become a symbol of the anti-tech, anti-Silicon Valley crowd. Surveys like this one demonstrate the American public’s general dislike and distrust of Google Glass. The product has not yet spawned an industry. It has not generated revenues for Google. It’s become a frequent joke on late night TV and a target for bloggers and comedians around the country. The world “glasshole” has now risen to the same prominence as “selfie” and “twerk.” Yes, it’s getting attention. But only as a creepy gimmick which, I’m sure, is not the kind of attention that Google intended when they initially introduced it. As cool as it is, let’s admit that Google Glass will go down in the annals of bad product launches. And it will do so because of these reasons.

For a limited time starting Tuesday, Google will make the wearable device available to more than just the select group of users such as apps developers in its Glass Explorer program.
In a blogpost, Google did not say how many pairs it would sell, just that the quantity would be limited.
"Every day we get requests from those of you who haven't found a way into the program yet, and we want your feedback too," the company said on a Thursday blogpost.
"That's why next Tuesday, April 15th, we'll be trying our latest and biggest Explorer Program expansion experiment to date. We'll be allowing anyone in the U.S. to become an Explorer by purchasing Glass."
Many tech pundits expect wearable devices to go mainstream this year, extending smartphone and tablet capabilities to gadgets worn on the body, from watches to headsets. Google has run campaigns in the past to drum up public involvement, including inviting people to tweet under the hashtag #ifihadglass for a chance to buy a pair of the glasses.
Google Glass has raised privacy concerns, prompting some legislators to propose bans on the gadget.
