Multics

In 1964, following implementation of the Compatible Time-Sharing System (CTSS) serious planning began on the development of a new computer system specifically organized as a prototype of a computer utility. The plans and aspirations for this system, called Multics (for Multiplexed Information and Computing Service), were described in a set of six papers presented at the 1965 Fall Joint Computer Conference. The development of the system was undertaken as a cooperative effort involving the Bell Telephone Laboratories (from 1965 to 1969), the computer department of the General Electric Company, and Project MAC of M.I.T.
