AT&T System V Unix (1991) 20 Unix

AT&T UNIX System V ("System Five"), first released in 1983, is significant as it was one of the first commercial versions of the Unix operating system. It was the result of much collaboration between vendors and became the core basis for many other operating systems including Xenix, AIX, UnixWare, Solaris, and HP-UX.

Banyan VINES (1992) 4 Unix

First released in 1984, Banyan VINES (Virtual Integrated NEtwork Service) was a network operating system originally designed for Unix, initially based on Xerox XNS. It was considered fairly lightweight both on clients and servers and used minimal bandwidth. It featured an early directory services system prior to either Novel or Microsoft.

Borland Enterprise Server (2001) 0 Windows Unix

Borland Enterprise Server was Borland's Java EE Application Server. The product was developed in 1999 within the team of former Visigenic company that was acquired by Borland in 1997. Borland's Java Studio was supposed to have BES and JBuilder tightly integrated, but in reality this integration never happened. BES suffered compatibility problems even with Borland's own products (JDataStore, OptimizeIt). The appearance of free commercial grade (and more mature) application servers, like JBoss, made BES unattractive and unable to really compete with the former.

Netscape Navigator/Communicator was the first commercial web browser, displacing the free NCSA Mosaic. 1.0 was first released in December 1994, and initially offered advanced features such as progressively rendering pages as they loaded. It quickly gained many other features and capabilities and became the most popular web browser in the mid 1990s. One reason for its popularity, it was licensed freely for personal and non-profit use, although companies were expected to pay for a license. It later competed with Microsoft Internet Explorer, Opera, and Safari, and eventually was open sourced in to the Mozilla browser.

NEWS-OS (1989) 0 Unix

NEWS-OS was a variant of BSD (later System version V UNIX) developed by Sony for use on their series of work stations called the Sony NEWS (Network Engineering WorkStation). This machine was a desktop replacement to VAXes in japan, created in 1987. NEWS-OS was designed specifically for use on computer networks, and had support for the TCP/IP protocol, something that wasn't commonly used back in the day but now required for today's machines. Versions 1-4 of NEWS-OS used 4.2BSD as its base. Versions 5 and 6 used UNIX System V 4.2.

Genera is a commercial operating system and integrated development environment for Lisp machines developed by Symbolics. It is essentially a fork of an earlier operating system originating on the Massachusetts Institute of Technology (MIT) AI Lab's Lisp machines which Symbolics had used in common with Lisp Machines, Inc. (LMI), and Texas Instruments (TI). Genera is also sold by Symbolics as Open Genera, which runs Genera on computers based on a Digital Equipment Corporation (DEC) Alpha processor using Tru64 UNIX. the programming language Lisp. software using a mix of programming styles with extensive support for object-oriented programming.

Sun Solaris (1989) 46 Unix

Solaris is a Unix based operating system created by Sun Microsystems (now purchased by Oracle in 2010). It is the successor to SunOS and was released initially in June of 1992. The OS is based off of System V Unix and its first release was known internally as SunOS 5. This OS was typically used on SPARC based processors, up until 1994 when it began to support x86 and x86-64 based machines. Versions of Solaris up until version 8 are considered abandoned, with version 9's support ending in October 2014.

Tru64 UNIX (1999) 8 Unix

Tru64, formerly Digital UNIX, formerly OSF/1 was DEC's UNIX product for their line of Alpha based systems. After DEC's acquisition by Compaq, it was renamed to Tru64. DEC previously had sold a BSD derivative named Ultrix for Vax and MIPS based systems. Their new UNIX on Alpha was meant to counter AT&T and Sun's SVR4 Unix. Tru64 / DIGITAL UNIX / OSF/1 is somewhat interesting in that it used portions of the Mach microkernel and BSD kernel and userland in a manner not entirely unlike NeXTSTEP or Mac OS X. Like OS X, Tru64 itself is not a microkernel system but uses Mach code in its kernel to implement threading and scheduling and possibly other features.
