UNIX is the moniker given to the family of trademarked multitasking multiuser computer operating systems that were originally part of the AT&T Unix program that was developed in the early 1970's. This operating system was originally devised by a team of researchers at the Bell Labs research center that included Ken Thompson and Dennis Richie. Created in mind initially for AT&T, the operating system was later loaned out to several outside parties in the latter half of 1970's.
