Mike Christie submitted a 1948 cite from John D. MacDonald's "School for the Stars"; originally we left this out, thinking that it was used here just as an abbreviation for "three-dimensional" (albeit in an science-fictional context) rather than to refer to a three-D television system or something similar. But after reflection we concluded that it was a real example for the sense 'a device that displays....'.

Many later cites are abbreviations for "three dimensional" in some broader context; we're not interested in these.
