A film trailer is a short video used to market upcoming feature films. It typically includes clips and scenes from the film designed to excite audiences and highlight the genre. Trailers have become popular online, so film companies create many trailers in hopes of going viral. The first movie trailer was created in 1914 to promote Charlie Chaplin's film "The Tramp." National Screen Service later contracted with film companies to produce trailers until the 1980s. Andrew J. Kuehn revolutionized film trailers in the 1960s with trailers for famous films like "Jaws" and "Indiana Jones," pushing boundaries of editing styles accepted by audiences.
