You were instead treated to a mix of shorts, newsreels, cartoons, and, eventually, trailers — which, per their name, played after the movie rather than before — with people coming and going throughout the day. The idea for trailers came from Nils Granlund, who in addition to being a business manager for movie theaters worked as a producer on Broadway, which explains why the first trailer was actually for a play: 1913’s The Pleasure Seekers.

Today there are production houses that exclusively make trailers and are handsomely rewarded for their efforts, sometimes to the tune of millions of dollars.
