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.
Feature film
In 1927, Warner Bros. released the first feature-length film with sound, "The Jazz Singer", whose audio track was recorded with a proprietary technology called Vitaphone. The film's success persuaded other studios to go to the considerable expense of adding microphones to their sets, and scramble to start producing their own "talkies".
