The Business Evolution of the Unix System: An account from the inside
by Otis Wilson
from the January 1985 issue of Unix Review magazine
Thanks to the developers of the UNIX operating system, and to the research method at AT&T Bell Laboratories, the technical evolution of the UNIX System has been well documented and its history largely understood.
