The purpose of a trailer is to promote and advertise films before they are released in cinemas. Early trailers consisted of key scenes and narration from films. In the 1960s, trailers began featuring quick editing and montages without narration. Today, longer trailers have replaced other pre-film entertainment, taking up about 20 minutes after the posted show time.

The term "trailer" comes from them having originally been shown at the end of a film program. This did not last long, because people tended to leave the theater after the films ended, but the name has stuck. Trailers are now shown before the film begins.
