In the ten-cent admission days theaters would run the trailers last (which is why they're called "trailers"), but you could stay as long as you wanted watching multiple showings of a single long feature, or a double or triple feature, a comedy short, a newsreel, a travelogue, et cetera, and sometimes even a live performance. In the silent days, the orchestra or the organist would play numbers between the films.

I'm thinking they should go back to the old business model of selling you a one-time (daily, weekly, or monthly) admission price for a varied all-day program, letting you stay as long as you like, and forcing you to pay for concessions, parking, blankets & pillows, toilets, et cetera, to make a profit.
