The name itself is a pun on Multics - Multics stands for ``Multiplexed Information and Computiny Service'', whereas ``Unics'' (later intentionally misspelled as ``Unix'') stands for ``Uniplexed Information and Computing Service''. This is because the system at first only supported a single user at a time.
That's not true. From the very beginning Unix was multi-user. The first implentation supported two simultaneous users.

From The Evolution of the UNIX Time-sharing System by D. M. Ritchie in the October, 1984 issue of the AT&T Bell Laboratories Technical Journal:
Quote:
Processes (independently executing entities) existed very early in PDP-7 UNIX. There were in fact precisely precisely two of them, one for each of the two terminals attached to the machine. There was no fork, wait, or exec. There was an exit, but it's meaning was rather different, as will be seen.
I love rereading these old papers. Every page is a gem. Driver, you'll love this quote... From Unix Time-Sharing System: A Retrospective by D. M. Ritchie in the July-August 1978 issue of the AT&T Bell Laboratories Technical Journal:
Quote:
One Problem in discussing the capabilities and deficiencies of UNIX is that there is no unique version of the system. It has evolved continuously both in time, and new functions are added and old problems repaired, and in space, as various organizations add features intended to meet their own needs. Four important versions of the unix system are in current use:
  • The standard system maintained by the Unix Support Group at Bell Laboratories for Bell System projects.
  • The "Programmer's Workbench" version, also in wide use within Bell Laboratories, especially in areas in which text-processing and job-entry to other machines are important. Recently PWB/UNIX has become available to outside organizations as well.
  • The "Sixth Edition" system (so called from the manual that describes it), which is most widely used under Western Electric licenses by organizations outside the Bell System.
  • The version currently used in the Computing Science Research Center, where the UNIX system was developed, and at a few other locations at Bell Laboratories
