23. A slide projector is an opto-mechanical
device for showing photographic slides.
35 mm slide projectors, direct descendants of
the larger-format magic lantern, first came
into widespread use during the 1950s as a

family members and friends would gather to
view slide shows, which typically consisted of
slidessnapped during vacations and at family
events
