!!! Overview
OS/2 was a series of computer [Operating Systems], initially created by [Microsoft] and [IBM] under the leadership of [IBM] software designer Ed Iacobucci.


As a result of a feud between the two companies over how to position OS/2 relative to [Microsoft]'s new [Windows Server 3].1 [Operating System], the two companies severed the relationship in [1992|Year 1992] and OS/2 development fell to [IBM] exclusively.

The name stands for "Operating System/2", because it was introduced as part of the same generation change release as [IBM]'s "Personal System/2 (PS/2)" line of second-generation personal computers. The first version of OS/2 was released in December [1987|Year 1987] and newer versions were released until December [2001|Year 2002].

OS/2 was intended as a protected mode successor of PC DOS. Notably, basic system calls were modelled after [MS-DOS] calls; their names even started with "Dos" and it was possible to create "Family Mode" applications: text mode applications that could work on both systems.

Because of this heritage, OS/2 shares similarities with [Unix], [Xenix], and [Windows Server NT].

[IBM] discontinued its support for OS/2 on 31 December [2006|Year 2006]. Since then, it has been updated, maintained and marketed under the name eComStation. In [2015|Year 2015] it was announced that a new OEM distribution of OS/2 would be released that was to be called [ArcaOS].
