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.
Dream Street (film)
The premiere engagement of the sound version of "Dream Street" took place on May 2, 1921 at Town Hall in New York City with Griffith's introduction. On May 15, the film reopened, now also with two other short sound sequences — Ralph Graves singing, and background noise in a scene showing a craps game. No other theaters could show the sound version of the film, since no other theaters had the Photokinema sound system installed.
