Evolution of movie trailer
so this next part ties in somewhat with the history part. this shows how trailers have changed and in turn, to a certain extent, how the audience evolved with the trailers.
Movie trailers have come a long way.
The trailers of old are very different from what we see today. Back in the old day a trailer would always try and sell the movie, but nowadays the trailer tries to sell itself, and inturn sells the movie. They are separate yet co-dependant. Appearing at key moments in movie trailer history, there are several trailers that helped develop the style of trailers that we see today. The first is the trailer for the movie La Dolce Vita. ( http://www.youtube.com/watch?v=-YyEuBPlgL0 )this trailer was rather different for its time, the trailer is a series of stills from the movie with a Congo beat. At the time this trailer offered a rather subdued alternative to the then common overkill tactic. The next is the trailer for the film Dr Strangelove. ( http://www.youtube.com/watch?v=1gXY3kuDvSU ) This trailer was a milestone in the movie trailer evolutionary process. This trailer is very strange and quite confusing, and by no means a good trailer, but this was the first trailer to use non-linear editing, the type of editing that we see in all modern movie trailers today. 
Another key point was the development of the Avid software in 1987,  which made non-linear editing much easier, instead of taking nearly an entire day to make a trailer, it could be done in half the time. 
Appearing at key moments in the evolutionary process, several trailers helped establish the developing style. For instance, the Dr. Strangelove trailer interspersed titles with scenes from the movie, pioneering a distinct new graphic feel. In 1960, Federico Fellini cut his own trailer for La Dolce Vita. By simply setting a series of stills to a congo beat, Fellini offered a relatively subdued alternative to the then-common overkill tactic and profoundly influenced the style of the time. 
“Everything has changed since we’ve gone to Avid,” says David Sameth, who oversees trailer production for DreamWorks. A decade earlier, Sameth worked with a radically different system of editing at Universal. “The basis of how you create a trailer, the thinking, might still be the same as it was when we cut on film, but it’s a whole different world when you go, ‘Should we try this? Well, it’ll take a day an a half,’ as opposed to, ‘Should we try this? Well, it’ll take 30 minutes.'” 
this is the list of all the trailers mentioned and a link to see them. they all have the title of the movie, the year and what i could and did use them for. also after it is the bibliography.
