Trailers are brief previews of upcoming films, shown on television, in cinemas, and online, to make audiences aware of new releases and attract them to watch. They showcase exciting clips and highlights to entice viewers. While trailers effectively promote films with a wide reach, some audiences may avoid them by skipping television ads or arriving late to cinemas. Institutions also benefit from the low cost of trailers compared to other marketing, but certain trailers may receive less airtime than others.
