In 1969,AT&T made a decision to withdraw Multics and go with GECOS. When Multics was withdrwan, Ken Thompson and Dennis Ritchie needed to rewrite an operating system in order to play space travel on another, smaller machine. The result was system which a punning colleague called UNICS(UNiplexed Information and Computing Service)- an 'enasculated Multics'.
