OS/2 was the originally result of a joint programming effort by Microsoft and IBM. It was intended as a sophisticated replacement for MSDOS which would be capable of running legacy MSDOS programs.

Early releases were slow, memory hungry and buggy leading to jokes such as "OS/2 = half an Operating System." Microsoft and IBM eventually went their own ways. IBM got OS/2 in the divorce. IBM went on to complete development and release usable versions in the early 1990s.

With native GUI support and multitasking support, good scripting and Windows 3 compatibility, OS/2 appeared to be a strong OS. The major user problems generally cited were a lack of hardware drivers for many devices, poor native software application support, and occasional need for complex tuning to get acceptable performance. However, few people actually used OS/2 because MSDOS/Windows 3 provided adequate support for most users. The advent of Windows 9x on the home side and NT on the business side would have required replication of a massive, poorly documented Applications Programming Interface to provide 32 bit Windows capability in OS/2. IBM opted not to provide that. General IBM support for OS/2 slowly faded and the OS was eventually allowed become largely moribund although limited support is still offered as of 2005 in order to support business users.
