Taligent

Taligent was a joint venture founded by Apple Computer and IBM in March 1992 to develop a next-generation operating system. HP announced in January 1994 that it would buy a 15% stake in Taligent. After failing to secure meaningful business, the company was dissolved in 1997.

History
Taligent originated in early 1986 as a project codenamed "Pink" at the Apple Advanced Technology Group. The development team was spun off in 1990 into Taligent to develop TalOS, a next-generation object-oriented operating system. A working demo of TalOS technology was prepared, but failed to attract business.

TalOS was due to be completed in 1995, but its engineering efforts were redirected. Parts of Taligent were used IBM's prototype. The frameworks of the Taligent OS became a layer called that could operate on top of AIX,,  and Windows NT.

Dissolution
In spring 1996, Taligent became a wholly-owned subsidiary of IBM. On September 16 1997, IBM announced that it would dissolve Taligent and transition the remaining software engineers into its laboratory in San Jose, California.
