Film Trailers

 

 

 

Definition

A trailer or preview is an advertisement or a commercial for a feature film that tends to be broadcasted  before the showing 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. Trailers for films have  become increasingly popular on DVDs and Blu-ray Discs, as well as online and on mobiles.
