When the first typesetter was procured typesetter roff aka troff, was born which assumes the C/A/T as the output device (which is a binary format). This is also were typesetter C comes from. Note these are 3 separate and different programs although nroff and troff mostly take the same input language. These were included in V5/6/7 IIRC When newer typesetters were obtained and after the death of troff’s author, Brian rewrote the nroff/troff package to create ditroff- device independent typesetter roff which also could support ASCII output nroff style This version was released independently of the OS and took a separate license. Ditroff was reimplemented by Clark (IIRC) to create today’s groff which takes mostly a superset of the ditroff input language.
