  USG Unix
  
     operating system /U-S-G yoo'niks/ Refers to AT&T Unix
     commercial versions after Version 7, especially System III
     and System V releases 1, 2, and 3.  So called because during
     most of the lifespan of those versions AT&T's support crew was
     called the "Unix Support Group".
  
     Compare BSD.
