108-458: Unix System Laboratories ( USL ), sometimes written UNIX System Laboratories to follow relevant trademark guidelines of the time, was an American software laboratory and product development company that existed from 1989 through 1993. At first wholly, and then majority, owned by AT&T , it was responsible for the development and maintenance of one of the main branches of the Unix operating system ,
216-503: A limited liability company . In a filing with the South Dakota Secretary of State dated January 30, 2024, the reason given for the merger is that New York state law does not allow AT&T Corp. to be directly converted into an LLC. Although acquired by SBC in 2005, AT&T Corp. has remained a separate entity within the corporate structure of AT&T Inc. The merger, said to create “greater operational efficiencies”, will end
324-453: A long distance subsidiary until its dissolution on May 1, 2024. AT&T started with Bell Patent Association , a legal entity established in 1874 to protect the patent rights of Alexander Graham Bell after he invented the telephone system. Originally a verbal agreement, it was formalized in writing in 1875 as Bell Telephone Company . In 1880 the management of American Bell created what would become AT&T Long Lines . The project
432-668: A $ 16,000 price per additional CPU. Apple Computer 's A/UX operating system was initially based on this release. SCO XENIX also used SVR2 as its basis. The first release of HP-UX was also an SVR2 derivative. Maurice J. Bach's book, The Design of the UNIX Operating System , is the definitive description of the SVR2 kernel. AT&T's UNIX System Development Laboratory (USDL) was succeeded by AT&T Information Systems (ATTIS), which distributed UNIX System V, Release 3, in 1987. SVR3 included STREAMS , Remote File Sharing (RFS),

The entire property was 130 acre and cost $ 219 million to construct. Later, across the street from the complex, AT&T purchased additional land and established its Learning Center in 1985, at 300 North Maple Avenue, to become
756-474: A Novell vice president who helped launch Univel, said the goal was to create a "Unix for the masses". A May 1992 InfoWorld interview with Pieper captured some of the ambitions of USL at the time, as Pieper said: "It is not just a new Unix version; rather it is the creation of an entire model change for Unix that says there are better ways to bring the benefits and features of Unix into a distributed PC environment. The earlier model did not allow Unix to play in
864-408: A continent-wide telephone system. On December 30, 1899, the assets of American Bell were transferred into its subsidiary American Telephone and Telegraph Company (formerly AT&T Long Lines ); this was because Massachusetts corporate laws were very restrictive, and limited capitalization to ten million dollars, forestalling American Bell's further growth. With this assets transfer at the very end of

In 1994, the project was completed and had one 34 ton granite boulder centered on top of the other boulders, which flowed water from the fountain designed by fountain engineer, Dr. Gerald Palevsky. AT&T occupancy at
1080-505: A dramatic shift from Unix to Linux: A look at the Top500 list of supercomputers tells the tale best. In 1998, Unix machines from Sun and SGI combined for 46% of the 500 fastest computers in the world. Linux accounted for one (0.2%). In 2005, Sun had 0.8% — or four systems — and SGI had 3.6%, while 72% of the Top500 ran Linux. In a November 2015 survey of the top 500 supercomputers, Unix

The property originally belonged to Western Union , of which AT&T held a controlling interest until 1913 when AT&T divested its interest as part of the Kingsbury Commitment . Construction of the current building began in 1912. Designed by William Welles Bosworth , who played a significant role in designing Kykuit ,
1404-645: A joint venture with Novell , called Univel . That year saw the release System V.4.2 as Univel UnixWare , featuring the Veritas File System . Other vendors included UHC and Consensys. Release 4.2MP, completed late 1993, added support for multiprocessing and it was released as UnixWare 2 in 1995. Eric S. Raymond warned prospective buyers about SVR4.2 versions, as they often did not include on-line man pages . In his 1994 buyers guide, he attributes this change in policy to Unix System Laboratories. The Santa Cruz Operation (SCO), owners of Xenix, eventually acquired
1512-416: A low-resource "embeddable" variant of UnixWare for dedicated commercial and industrial applications, in an attempt that was perceived as a response to the growing popularity of Linux. The industry has since coalesced around The Open Group 's Single UNIX Specification version 3 ( UNIX 03 ). In the 1980s and 1990s, a variety of SVR4 versions of Unix were available commercially for the x86 PC platform. However,
1620-445: A message could pay a "toll" to AT&T and then air the message publicly. The original studio was the size of a telephone booth. The idea, however, did not take hold, because people would pay to broadcast messages only if they were sure that someone was listening. As a result, WEAF began broadcasting entertainment material, drawing amateur talent found among its employees. Opposition to AT&T's expansion into radio and an agreement with
1728-468: A new building at 550 Madison Avenue . This new AT&T Building was designed by Philip Johnson and quickly became an icon of the new Postmodern architectural style. The building was completed in 1984, the very year of the divestiture of the Bell System. The building proved to be too large for the post-divestiture corporation and in 1993, AT&T leased the building to Sony , who then subsequently owned
1836-642: A new president and CEO in November 1991 when Dooling was replaced by the Dutchman Roel Pieper , formerly chief technical officer of Software AG . USL was aggressive in defending its perceived intellectual property rights, initiating as the plaintiff a lawsuit in 1992 against Berkeley Software Design makers of and the Regents of the University of California over copyrights and trademarks related to Unix. The case
1944-606: A sale-leaseback agreement valued at $ 650.3 million on the complex with the address previously known as One Verizon Way. In 2017, the 35 acre hotel/conference center was known as the Dolce Basking Ridge Hotel and sold for $ 30 million. On February 15, 2024, AT&T Inc. filed notice with the Kentucky Public Service Commission that it intends to make an internal structural change and merge AT&T Corp. into AT&T Enterprises, Inc., which will become
2052-565: A source code product to its partners, in working to define industry standards such as POSIX, and in making decisions on the direction of Unix based on technical merit not corporate advantage – paved the way for the rise of a Unix-like entity such as the Linux operating system, and that this beneficial historical role has been obscured by the SCO–Linux controversies. AT%26T Corporation AT&T Corporation , an abbreviation for its former name,
2160-435: A stronghold there, in part because USL's third-party licensing payment obligations made low-cost sales uneconomical, and in part because of a lack of applications to run on UnixWare. On December 21, 1992, it was announced that Novell would acquire Unix System Laboratories, and all of its Unix assets, including all copyrights, trademarks, and licensing contracts, for some $ 335 million in stock. The news led to large headlines of
2268-467: A subsequent press release stated, "in order to separate AT&T's UNIX System source code business from its computer systems business," the latter a reference to AT&T Computer Systems . USO included the AT&;T Data Systems Group organizations responsible for UNIX product planning and management, licensing, and marketing. Peter J. Weinberger was named chief scientist of USO while also retaining his job in

A joint project of AT&T Unix System Laboratories and Sun Microsystems , it combined technology from: New features included: Many companies licensed SVR4 and bundled it with computer systems such as workstations and network servers . SVR4 systems vendors included Atari ( Atari System V ), Commodore ( Amiga Unix ), Data General ( DG/UX ), Fujitsu ( UXP/DS ), Hitachi (HI-UX), Hewlett-Packard (HP-UX), NCR ( Unix/NS ), NEC ( EWS-UX , UP-UX, UX/4800, SUPER-UX ), OKI (OKI System V), Pyramid Technology ( DC/OSx ), SGI ( IRIX ), Siemens ( SINIX ), Sony ( NEWS-OS ), Sumitomo Electric Industries (SEIUX), and Sun Microsystems ( Solaris ) with illumos in
2592-608: Is called a "hypostyle hall", with full-bodied Doric columns modeled on the Parthenon, marking out a grid. Bosworth was seeking to coordinate the classical tradition with the requirements of a modern building. Columns were not merely the decorative elements they had become in the hands of other architects but created all the illusion of being real supports. Bosworth also designed the campus of MIT as well as Theodore N. Vail 's mansion in Morristown, New Jersey . In 1978, AT&T commissioned
2700-421: Is one of the first commercial versions of the Unix operating system . It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as Unix System Unification , which solicited the collaboration of the major Unix vendors. It

On April 30, 1907, Theodore Newton Vail became President of AT&T. Vail believed in the superiority of one phone system and AT&T adopted the slogan "One Policy, One System, Universal Service." This would be the company's philosophy for
3132-778: The UNIX System V Release 4 source code product. Through Univel , a partnership with Novell , it was also responsible for the development and production of the UnixWare packaged operating system for Intel architecture . In addition it developed Tuxedo , a transaction processing monitor , and was responsible for certain products related to the C++ programming language . USL was based in Summit, New Jersey , and its CEOs were Larry Dooling followed by Roel Pieper . Created from earlier AT&T entities, USL was, as industry writer Christopher Negus has observed,
3240-548: The "NOVELL BUYS UNIX" variety. The measure was intended to help Novell compete against Microsoft , which was on the verge of including networking as a built-in feature of Windows in conjunction with the Windows NT server. It was also an outgrowth of Novell chief Ray Noorda 's theories about coopetition in a technology industry. The move seemed like a long shot to analysts, with a commentary piece in Computerworld outlining

3456-519: The 1980s and early-1990s, UNIX System V and the Berkeley Software Distribution (BSD) were the two major versions of UNIX. Historically, BSD was also commonly called "BSD Unix" or "Berkeley Unix". Eric S. Raymond summarizes the longstanding relationship and rivalry between System V and BSD during the early period: In fact, for years after divestiture the Unix community was preoccupied with
3564-492: The 19th century, AT&T became the parent of both American Bell and the Bell System . AT&T was involved mainly in the telephone business and, although it was a partner with RCA , was reluctant to see radio grow because such growth might diminish the demand for wired services. It established station WEAF in New York as what was termed a toll station . AT&T could provide no programming, but anyone who wished to broadcast

SVR4 software vendors included Dell (Dell UNIX), Everex (ESIX), Micro Station Technology (SVR4), Microport (SVR4), and UHC (SVR4). The primary platforms for SVR4 were Intel x86 and SPARC ; the SPARC version, called Solaris 2 (or, internally, SunOS 5.x), was developed by Sun. The relationship between Sun and AT&T
3780-476: The AT&T and Sun sides. System V Release 4 debuted at the Unix Expo trade show in New York in November 1989, in the form of source code availability for it as well as demonstrations from Unix International of SVR4-based applications running on seventeen different vendor platforms. End-user versions of Release 4 became available during 1990. Next USL engaged in an especially arduous effort into trying to satisfy
3888-593: The Bell-internal CB UNIX . SVR1 ran on DEC PDP-11 and VAX minicomputers . AT&T's UNIX Support Group (USG) transformed into the UNIX System Development Laboratory (USDL), which released System V Release 2 in 1984. SVR2 added shell functions and the SVID . SVR2.4 added demand paging , copy-on-write , shared memory , and record and file locking . The concept of the "porting base"
3996-522: The C++ language in Bell Labs and became widely used internally within AT&T, by one estimate being used in hundreds of projects. They represented an effort among early library writers there to design reusable code using C++ idioms. Unlike its other offerings, which were sold to OEM vendors and resellers, here USL sold to end users. The initial release of USL C++ Standard Components to the general computing industry
4104-594: The File System Switch (FSS) virtual file system mechanism, a restricted form of shared libraries , and the Transport Layer Interface (TLI) network API . The final version was Release 3.2 in 1988, which added binary compatibility to Xenix on Intel platforms (see Intel Binary Compatibility Standard ). User interface improvements included the "layers" windowing system for the DMD 5620 graphics terminal, and

4536-722: The UNIX Software Operation was publicly rebranded as UNIX System Laboratories. Again, a point of emphasis was to separate the Unix-based business from AT&T's hardware-based business. The subsidiaries were known as UNIX System Laboratories Europe, Ltd., sited near Ealing Broadway in London , and UNIX System Laboratories Pacific, Ltd., located in Shiba, Tokyo . Dooling was named the initial president of USL, continuing from his position at USO. These organizational changes were taking place in
4644-629: The UNIX System V Software business unit and headed by Michael J. DeFazio, was responsible for the development of the UNIX System V base technology. DeFazio had held a similar role within USO. The USO/USL staff was heavily involved in the creation of UNIX System V Release 4 , which shipped in 1989 and was a joint project with Sun Microsystems . This work incorporated technology from a variety of Unix-based efforts, including UNIX System V , BSD , and Xenix . There were additions and new innovations as well from both

AT&T had a domestic and global presence in laying the infrastructure of undersea routes for telecommunications. In 1950, the U.S. Navy commissioned a network of undersea surveillance cables for foreign submarine detection. AT&T was probably, according to internal employees, involved in this Sound Surveillance System ( SOSUS ). After completion, AT&T began commercial operations in cable laying for communications in 1955. The implementation of cables assured local and long-distance telephone or data services would provide revenue for

AT&T announced the creation of the UNIX Software Operation (USO) – a separate and distinct AT&T business unit responsible for the development, marketing, and licensing of UNIX System V software – in January 1989. This was done, as
5940-684: The deal was finalized in June 1993. Novell created the Unix Systems Group to contain the new business, which also absorbed the Univel venture. Rekhi was named as the head of the Unix Systems Group. Pieper, who had been assigned under Rekhi with little role to play, soon departed, leaving Novell in August 1993. The USL Europe office in London was moved into Novell's facility in Bracknell, Berkshire . The Chorus work it

In another interview around the same time, Pieper predicted that if the new Unix became a success, USL revenue could increase ten-fold to $ 1 billion within five years. Pieper acknowledged that similar Unix efforts had failed in
7560-462: The market for commercial Unix on PCs declined after Linux and BSD became widely available. In late 1994, Eric S. Raymond discontinued his PC-clone UNIX Software Buyer's Guide on USENET , stating, "The reason I am dropping this is that I run Linux now, and I no longer find the SVr4 market interesting or significant." In 1998, a confidential memo at Microsoft stated, "Linux is on track to eventually own
7668-520: The market were IBM AIX, Hewlett-Packard's HP-UX, and Sun's Solaris. In 2006, when SGI declared bankruptcy, analysts questioned whether Linux would replace proprietary Unix altogether. In a 2006 article written for Computerworld by Mark Hall, the economics of Linux were cited as a major factor driving the migration from Unix to Linux: Linux's success in high-end, scientific and technical computing , like Unix's before it, preceded its success in your data center . Once Linux proved itself by executing
7776-462: The most complex calculations possible, IT managers quickly grasped that it could easily serve Web pages and run payroll . Naturally, it helps to be lucky: Free, downloadable Linux's star began to rise during one of the longest downturns in IT history. With companies doing more with less, one thing they could dump was Unix. The article also cites trends in high-performance computing applications as evidence of
7884-470: The next 70 years. Under Vail, AT&T began buying up many of the smaller telephone companies including Western Union telegraph . These actions brought unwanted attention from antitrust regulators. Anxious to avoid action from government antitrust suits, AT&T and the federal government entered into an agreement known as the Kingsbury Commitment . In the Kingsbury Commitment, AT&T and
7992-515: The obstacles to success and stating, "Saying this deal has the technical potential to counter Windows NT is very different from predicting that it will do so." There was negative reaction to the acquisition from USL shareholders, USL employees, and members of Unix International. Noorda had to emphasize that Novell had no plans to move USL operations from New Jersey to Utah, where Novell was based. And Noorda and Pieper had to travel to Japan to reassure USL shareholders and investors there. Nonetheless,
8100-410: The original 22 subsidiaries that formed AT&T Communications continue to exist. AT&T Laboratories has been integrated into AT&T Labs , formerly named SBC Laboratories . AT&T was also known as "Ma Bell" and affectionately called "Mother" by phone phreaks . During some strikes by its employees, picketers would wear T-shirts reading, "Ma Bell is a real mother." Before the break-up, there
8208-476: The past, but said that the presence of Novell's PC presence and marketing experience as well as the interest of Intel would make the difference this time. Indeed, Pieper had aspirations to be another Bill Gates : "I want to be in the same position." UnixWare 1.0, which is what Destiny became a product as, was announced on October 12, 1992. It was based on the Unix System V release 4.2 kernel. The MoOLIT toolkit
8316-540: The publication of an early Unix standard, the System V Interface Definition (SVID). Moreover, the SVID became one of the bases for the more important, vendor-independent POSIX standard for Unix, which System V Release 4 releases also conformed to, as well as the later Single UNIX Specification . USL produced many books documenting various aspects of Unix System V. USL also provided some training and consulting services for Unix systems. In 1991, USL forged an arrangement with
8424-472: The radically different Standard Template Library (STL), which became the standardized foundation library for the C++ language. As it happens, one of the Standard Components, array_alg, was designed by the creator of STL, Alex Stepanov , and can be considered an early predecessor of STL. In April 1991, USL became partly independent of AT&T when about 22 percent of it, worth about $ 65 million,
8532-570: The requirements of the National Computer Security Center 's Trusted Computer System Evaluation Criteria ("Orange Book") to the B2 level. This manifested itself in System V Release 4.1 ES (Enhanced Security), which also included generally useful features such as support for dynamic loading of kernel modules. Following that, USL worked on System V Release 4.2 , which was released in June 1992. InfoWorld characterized this effort as "at
8640-657: The sale of Unix to the Santa Cruz Operation , coincident with a licensing arrangement with Hewlett-Packard , in September 1995. Following another change of ownership, the renamed The SCO Group and the Unix System V source base became elements of the SCO–Linux disputes . After The SCO Group went bankrupt, the SCO products using the Unix System V source base were purchased by UnXis, later renamed to Xinuos . Although it never took off within
8748-649: The specification and inspection of non Bell System cable for networks such as the TAT-2 . By the continuous undersea network installations, AT&T was a globally technology leader with the 1970 installed TAT-5 and the 1975 installed TAT-6 , achieving 720 channels and then 4000 channels for transmitting voice or data. Prior to 1963, AT&T had to charter oceanic ships, such as the CS Monarch (1945) for installations. AT&T purchased CS Long Lines in 1961 and operated it with several cable laying ships that would provide, either
8856-597: The standard among Unix users at the time of development, while PC networking was much more commonly based on the highly successful NetWare product; indeed, the base level of the Personal Edition of UnixWare did not even have TCP/IP included, while the Application Server version did. Initial sales of UnixWare were underwhelming, with Unix facing a difficult time in the PC market. This was in part because Windows already had
8964-471: The subcontractor. The 295 North Maple Avenue and Interstate 287 location of Basking Ridge in Bernards Township , New Jersey was completed in 1975 for the AT&T General Department offices. Employees began moving, in November 1975, to the seven inter-connected building complex using 28 acre of the property. The property had a 15-acre underground parking garage with spaces for 3,900 vehicles, and included
9072-458: The view of writer Christopher Negus, "The UNIX Laboratory was considered a jewel that couldn't quite find a home or a way to make a profit. As it moved between Bell Laboratories and other areas of AT&T, its name changed several times. It is probably best remembered by the name it had as it began its spin-off from AT&T: UNIX System Laboratories (USL)." However Negus believes that in three crucial respects USL's actions – in continuing to release
9180-576: The work was still ongoing, with questions of industry standardization of interfaces arising. Unisys was also part of the collaboration effort. Announcements made during 1993 promised an OEM release in 1994 and a general availability release in 1995. This was part of the larger Ouverture project , a $ 14 million effort that was itself part of the European Strategic Program on Research in Information Technology (ESPRIT), overseen by
9288-410: The x86 UNIX market", and further predicted, "I believe that Linux – moreso than NT – will be the biggest threat to SCO in the near future." An InfoWorld article from 2001 characterized SCO UnixWare as having a "bleak outlook" due to being "trounced" in the market by Linux and Solaris, and IDC predicted that SCO would "continue to see a shrinking share of the market". Project Monterey
9396-603: Was forked into proprietary release, but illumos as the continuation project is being developed in open-source. A consortium of Intel-based resellers including Unisys , ICL , NCR Corporation , and Olivetti developed SVR4.0MP with multiprocessing capability (allowing system calls to be processed from any processor, but interrupt servicing only from a "master" processor). Release 4.1 ES (Enhanced Security) added security features required for Orange Book B2 compliance and Access Control Lists and support for dynamic loading of kernel modules. In 1992, AT&T USL engaged in
9504-581: Was changed from the 12-line design to the 8-line design. Again in 2005 it was changed to the 3D transparent "marble" design created by Interbrand for use by the parent company AT&T Inc. This name was also given to the iconic Bell Labs facility in Holmdel, New Jersey , now a multi-tenant office facility. The following is a list of the 16 CEOs of AT&T Corporation, from its incorporation in 1885 until its purchase by SBC Communications in 2005. UNIX System V Unix System V (pronounced: "System Five")
9612-489: Was developed by AT&T's UNIX Support Group (USG) and based on the Bell Labs internal USG UNIX 5.0. System V also included features such as the vi editor and curses from 4.1 BSD, developed at the University of California, Berkeley ; it also improved performance by adding buffer and inode caches. It also added support for inter-process communication using messages, semaphores , and shared memory , developed earlier for
9720-734: Was divided between IBM (56%), Oracle (19.2%), and HP (18.6%). No other commercial Unix vendor had more than 2% of the market. Industry analysts generally characterize proprietary Unix as having entered a period of slow but permanent decline. OpenSolaris and its derivatives are the only SVR4 descendants that are open-source software . Core system software continues to be developed as illumos used in illumos distributions such as SmartOS , Omniosce , OpenIndiana and others. The System V interprocess communication mechanisms are available in Unix-like operating systems not derived from System V; in particular, in Linux (a reimplementation of Unix) as well as
9828-486: Was doing became the basis for the Novell " SuperNOS ", a project to create a microkernel-based, UnixWare–NetWare hybrid, network operating system. The acquisition of USL never really worked out for Novell, and was followed by Novell's misguided acquisitions of WordPerfect and Quattro Pro in another attempt to compete head-to-head with Microsoft. In particular, the "SuperNOS" project never achieved fruition. Novell announced
9936-467: Was formalized, and the DEC VAX-11/780 was chosen for this release. The "porting base" is the so-called original version of a release, from which all porting efforts for other machines emanate. Educational source licenses for SVR2 were offered by AT&T for US$ 800 for the first CPU, and $ 400 for each additional CPU. A commercial source license was offered for $ 43,000, with three months of support, and
10044-503: Was greater consumer recognition of the "Bell System" name, in comparison to the name AT&T. This prompted the company to launch an advertising campaign after the break-up to increase its name recognition. Spinoffs like the Regional Bell Operating Companies or RBOC s were often called "Baby Bells". Ironically, "Ma Bell" was acquired by one of its "Baby Bells", SBC Communications , in 2005. The AT&T Globe Symbol,
10152-452: Was known as UNIX System Laboratories, Inc. v. Berkeley Software Design, Inc. and in it USL asked the court for a preliminary injunction that would bar the Berkeley firm and the university from distributing their Net/2 operating system release, which was implied to be Unix, until the case was concluded. In response the university filed a countersuit against AT&T for alleged breaches in
10260-408: Was known as SF for Summit Facility. UNIX System Laboratories, Inc., came into being as a separate subsidiary of AT&T in November 1989 and was assigned all U.S.-based AT&T Unix and USO assets. However USO continued to operate as USO until June 1990, when the reincorporation of AT&T's European and Asian Unix business operations as wholly owned subsidiaries of USL was completed. At that point
10368-545: Was labelled as Release 2.0 and occurred in 1991; it suffered from an awkward mechanism to get around the lack of templates in the container classes. That was followed by Release 3.0, which added support for templates, in 1992. Some within USL believed that C++ Standard Components could become a language standard as well as a significant source of revenue, but it had trouble gaining traction outside of AT&T. Stroustrup would later describe these goals as "a misguided belief". In any case, all such libraries were soon eclipsed by
10476-453: Was listed 73 times in cable laying operations for specific routes deployed. The Cable Ship Long Lines had 23 cable runs from 1963 to 1992, with the first deep-sea trial of optical fiber cable in 1982 leading to the consortium of countries and locations for the TAT-8 fiber cable implementation of 1988. The United States Justice Department opened the case United States v. AT&T in 1974. This
10584-400: Was prompted by suspicion that AT&T was using monopoly profits from its Western Electric subsidiary to subsidize the cost of its network, a violation of antitrust law. A settlement to this case was finalized in 1982, leading to the division of the company on January 1, 1984, into seven Regional Bell Operating Companies , commonly known as Baby Bells. These companies were: Post-breakup,
10692-541: Was renamed Lucent Technologies . Lucent was completely spun off from AT&T in 1996. On January 31, 2005, the " Baby Bell " company SBC Communications announced its plans to acquire " Ma Bell " AT&T Corp. for $ 16 billion. SBC announced in October 2005 that it would shed the "SBC" brand and take the more recognizable AT&T brand, along with the old AT&T's "T" NYSE ticker symbol. Merger approval concluded on November 18, 2005; SBC Communications began rebranding
10800-644: Was responsible for the C language compiler and development tools used to build Unix. Moreover, it was responsible for commercial sales related to the C++ language, including development tools such as the Cfront compiler that had come from AT&T. Indeed, the paper describing one of the first implementations of automatic instantiation of C++ templates in a C++ compiler had as lead author an engineer associated with Unix System Laboratories. And Margaret A. Ellis , co-author with C++ creator Bjarne Stroustrup of The Annotated C++ Reference Manual , an important publication in
10908-536: Was responsible for the innovations of products or technologies in cabling in transmission by undersea systems. In 1955, the first trans-Atlantic telephone undersea cable, TAT-1 , from North America to Europe was installed by AT&T. This installation allowed 48 telephone circuits to be used for long-distance calling. When partnering with other global Telecommunications companies, such as the French Cables de Lyon and German Felten & Guilleaume , Bell Labs provided
11016-470: Was sold to eleven outside computer vendors: Amdahl , Motorola , Novell, Sun, ICL , Olivetti , Fujitsu , NEC , OKI Electric , Toshiba , and the Institute for Information Industry . There was a stated goal to lessen the control AT&T had over Unix, which would lead to USL becoming a publicly owned company within three years. An AT&T executive said, "AT&T is convinced that the best way to nurture
11124-504: Was started in 1998 to combine major features of existing commercial Unix platforms, as a joint project of Compaq , IBM, Intel, SCO, and Sequent Computer Systems . The target platform was meant to be Intel's new IA-64 architecture and Itanium line of processors. However, the project was abruptly canceled in 2001 after little progress. By 2001, several major Unix variants such as SCO UnixWare, Compaq Tru64 UNIX , and SGI IRIX were all in decline. The three major Unix versions doing well in
11232-399: Was terminated after the release of SVR4, meaning that later versions of Solaris did not inherit features of later SVR4.x releases. Sun would in 2005 release most of the source code for Solaris 10 (SunOS 5.10) as the open-source OpenSolaris project, creating, with its forks, the only open-source (albeit heavily modified) System V implementation available. After Oracle took over Sun, Solaris
11340-466: Was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure. The project was formally incorporated in New York as a separate company named American Telephone and Telegraph Company on March 3, 1885. Originating in New York City, its long-distance telephone network reached Chicago, Illinois , in 1892, with its multitudes of local exchanges continuing to stretch further and further yearly, eventually creating
11448-474: Was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV . As of 2021 , the AT&T-derived Unix market is divided between four System V variants: IBM 's AIX , Hewlett Packard Enterprise 's HP-UX and Oracle 's Solaris , plus the free-software illumos forked from OpenSolaris . System V was the successor to 1982's UNIX System III . While AT&T developed and sold hardware that ran System V, most customers ran
11556-413: Was used by only 1.2% (all running IBM AIX), while Linux was used by 98.8%; the same survey in November 2017 reports 100% of them using Linux. System V derivatives continued to be deployed on some proprietary server platforms. The principal variants of System V that remain in commercial use are AIX (IBM), Solaris (Oracle), and HP-UX (HP). According to a study done by IDC , in 2012 the worldwide Unix market
11664-589: Was used for the windowing system , allowing the user to choose between an OPEN LOOK or MOTIF -like look and feel at run time. In order to make the system more robust on commodity desktop hardware the Veritas VXFS journaling file system was used in place of the UFS file system used in SVR4. Networking support in UnixWare included both TCP/IP and interoperability with Novell's NetWare protocols of IPX/SPX . The former were
