Movie trailers are a common staple of the film industry in today's times. Many people have stopped and asked themselves "Why are they call trailers if they are shown before the film?" The reason behind this is that in the beginning trailers were originally shown at the very end of movies. In the early days the credits were shown at the beginning of movies so when "The End" appeared the movie was over. Theater owners thought that by showing two feature films they would have time to advertise up and coming releases between the two. None the less this practice lasted only for a short while due to patrons leaving early, but the name stuck even though film trailers are shown at the beginning of movies now. Trailers are a compilation of a few shots from a film in order to advertise. The sole purpose of a movie trailer is to attract an audience to come back to the theater and see a film coming out at a later date. They are usually comprised of exerts from the most noteworthy parts of the film and not to "spoil it" the scenes are not always place in the order in which they appear. All is done in less than two and a half minutes which is the maximum time allowed by the MPAA. The very first movie trailer to appear was in November of 1913 by Nils Granlund. He created a promotional piece for a musical opening at the Winter Garden Theater on Broadway named "The Pleasure Seekers." Granlund was the advertising manager for the Marcus Lowe theater chain. They were to be show at all of Lowe's picture houses and many believed that they would take the place of billboard advertising. It was common practice prior to the 1950s that most trailers contained an array of scenes with descriptive text describing the action. Most if not all contained a narrator. The 1960s is when the standard movie trailer changed. No more words but a montage of action and quick editing became the norm for movies and television. Now trailer and video have become a great way for film companies to market movies that are "coming soon".
