>> PostScript, which was once widely used

> in academia. Not outside.

NeXTSTEP utilized "Display PostScript"[0] for both printing and display. Apple's Cocoa can trace direct ancestry to frameworks originating in NeXTSTEP[1]. I am pretty sure this included use of PostScript in the display/printing frameworks as well, but do not have references to support that memory.

So, while '.ps' files are not often seen in the wild, as you say, a strong case can be made that PostScript was once (if not currently) widely used.
