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.

Parallel with improvements in sound-on-film technology, a number of companies were making progress with systems that recorded movie sound on phonograph discs. In sound-on-disc technology from the era, a phonograph turntable is connected by a mechanical interlock to a specially modified film projector, allowing for synchronization. In 1921, the Photokinema sound-on-disc system developed by Orlando Kellum was employed to add synchronized sound sequences to D. W. Griffith's failed silent film "Dream Street". A love song, performed by star Ralph Graves, was recorded, as was a sequence of live vocal effects. Apparently, dialogue scenes were also recorded, but the results were unsatisfactory and the film was never publicly screened incorporating them. On May 1, 1921, "Dream Street" was re-released, with love song added, at New York City's Town Hall theater, qualifying it—however haphazardly—as the first feature-length film with a live-recorded vocal sequence. There would be no others for more than six years.
In 1925, Sam Warner of Warner Bros., then a small Hollywood studio with big ambitions, saw a demonstration of the Western Electric sound-on-disc system and was sufficiently impressed to persuade his brothers to agree to experiment with using this system at New York's Vitagraph Studios, which they had recently purchased. The tests were convincing to the Warner Brothers, if not to the executives of some other picture companies who witnessed them. Consequently, in April 1926 the Western Electric Company entered into a contract with Warner Brothers and W. J. Rich, a financier, giving them an exclusive license for recording and reproducing sound pictures under the Western Electric system. To exploit this license the Vitaphone Corporation was organized with Samuel L. Warner as its president.
Vitaphone, as this system was now called, was publicly introduced on August 6, 1926, with the premiere of "Don Juan"; the first feature-length movie to employ a synchronized sound system of any type throughout, its soundtrack contained a musical score and added sound effects, but no recorded dialogue—in other words, it had been staged and shot as a silent film. Accompanying "Don Juan", however, were eight shorts of musical performances, mostly classical, as well as a four-minute filmed introduction by Will H. Hays, president of the Motion Picture Association of America, all with live-recorded sound. These were the first true sound films exhibited by a Hollywood studio. Warner Bros.' "The Better 'Ole", technically similar to "Don Juan", followed in October.
