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.
Raquel Meller
The sight and sound of Meller were captured for the Fox Movietone sound system, first demonstrated to the public at the Sam H. Harris Theatre in New York City on 21 January 1927. The clip, not quite synchronized, was shown by a movie projector equipped to play sound-on-film, and preceded the feature film "What Price Glory?" originally released by Fox in November 1926.
