C mount was most commonly used for 16mm movie cameras, and later for TV
cameras. Later on, when "zoom" lenses became popular, lens
interchangeability faded away, with the assumption that nobody would ever
want anything other than what came with the camera. Kinda like the early
Macs.

D mount was used for 8mm movie camera. Like C mount, it was replaced with
non-removable "zoom" lenses.

Oh, well.

Most people would. I reserve the word "large" for 5 x 7, 8 x 10, and
above.

There are uses for both. There are some situations appropriate for each.
For example: low res, TEMPORARY pictures, for web or email can be done
more conveniently with a digital. But I'm NOT about to get rid of my old
35mm cameras and lenses, nor medium, nor large format cameras.
