Trailers use montage editing to highlight key parts of a film and advertise it to audiences, generating interest. They are shown widely on televisions, in cinemas, and on DVDs to reach a broad market and expose audiences to the film at every opportunity, aiming to make it popular and successful upon release. Title sequences introduce the name of a film or program, list actors and crew, and begin engaging audiences with questions to hook their interest through continuity editing rather than montage.
