Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Opening credits
The first sound film to begin without any opening credits was Walt Disney's "Fantasia", released in 1940. In the film's general release, a title card and the credit "Color by Technicolor" were spliced onto the beginning of the film, but otherwise there were no credits, although closing credits were added to the 1990 re-release and are on the videocassette. This general release version has been the one most often seen by audiences. In the roadshow version of the film, unseen by most audiences until its DVD release, the title card is seen only at the halfway point of the film, as a cue that the intermission is about to begin. The intermission was omitted in the general release version.
