A trailer or preview is an advertisement or a commercial for a feature film that will be exhibited in the future at a cinema. The term "trailer" comes from their having originally been shown at the end of a feature film screening. That practice did not last long, because patrons tended to leave the theater after the films ended, but the name has stuck. Trailers are now shown before the film (or the A movie in a double feature) begins.

Movie trailers have now become popular on DVDs and Blu-ray Discs, as well as on the Internet and Mobile devices. Of some 10-billion videos watched online annually, film trailers rank #3, after news and user-created video.

The first trailer shown in a U.S. film theater was in November 1913, when Nils Granlund, the advertising manager for the Marcus Loew theater chain, produced a short promotional film for the musical The Pleasure Seekers, opening at the Winter Garden Theatre on Broadway. Loew adopted the practice, which was reported in a wire service story carried by the Lincoln, Nebraska Daily Star, describing it as "an entirely new and unique stunt", and that "moving pictures of the rehearsals and other incidents connected with the production will be sent out in advance of the show, to be presented to the Loew’s picture houses and will take the place of much of the bill board advertising". Granlund was also first to introduce trailer material for an upcoming motion picture, using a slide technique to promote an upcoming film featuring Charlie Chaplin at Loew's Seventh Avenue Theatre in Harlem in 1914. Up until the late 1950s, trailers were mostly created by National Screen Service and consisted of various key scenes from the film being advertised, often augmented with large, descriptive text describing the story, and an underscore generally pulled from studio music libraries. Most trailers had some form of narration and those that did featured stentorian voices.
