My response along the following lines seems to have gone astray.
The prime reason for Unix was the desire of Ken, Dennis, and Joe
Ossanna to have a pleasant environment for software development.
The fig leaf that got the nod from Multics-burned management was
that an early use would be to develop a "stand-alone" word-processing
system for use in typing pools and secretarial offices. Perhaps they
had in mind "dedicated", as distinct from "stand-alone"; that's
what eventuated in various cases, most notably in the legal/patent
department and in the AT&T CEO's office.
Both those systems were targets of opportunity, not foreseen from the
start. When Unix was up and running on the PDP-11, Joe got wind of
the legal department having installed a commercial word processor.
He went to pitch Unix as an alternative and clinched a trial by
promising to make roff able to number lines by tomorrow in order to
fulfill a patent-office requirement that the commercial system did
Modems were installed so legal-department secretaries could try the
Research machine. They liked it and Joe's superb customer service.
Soon the legal department got a system of their own. Joe went on to
create nroff and troff. Document preparation became a widespread use
of Unix, but no stand-alone word-processing system was ever undertaken.
