Film Trailers and the Selling of Hollywood Technology

The audience’s first exposure to a new movie is often in the form of a "coming attraction" trailer, and short previews are also a vanguard for emerging technology and visual techniques. This book demonstrates how the trailer has educated audiences in new film technologies such as synchronized sound, widescreen and 3-D, tracing the trailer’s status as a trailblazer on to new media screens and outlets such as television, the Internet, and the i Pod. The impact and use of new technologies and the evolution of trailers beyond the big screen is followed into the digital era.
