I know that there were actual commercial companies selling them, but where those mostly university spinoffs selling back to universities? I would think that roughly 10000 hardware Lisp machines were built (incl. embedded boards). Quite a lot went into research, but not just academic research, but also company R&D. Some machines were built as deployment machines and were used by military, government agencies (like NASA) and also commercial. Notable were for example the graphics systems by Symbolics which were widely used in high-end graphics for TV and animation studios. A lot of computer animated logos you were seeing in TV in the mid/end 80s were done with them.
