'''OS/2''' ('''Operating System/2''') is an operating system originally developed jointly by [[w:Microsoft|Microsoft]] and IBM, in development was codenamed "CP/DOS". Between the release of [[Windows 3.0]] and [[OS/2 1.3]], Microsoft stopped all cooperation with IBM, due to a feud between the companies' significantly different cultures and visions. IBM later on handled the development of the operating system by itself.
