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.

After the release of "The Jazz Singer" in 1927—the first feature-length film with some audible dialog—sound films, or talkies, as they became nicknamed, were all the rage. The transition from silent to sound panicked many, if not all, involved with the film industry; many silent film stars found themselves unemployable because of their undesirable voices and hard-to-understand accents, or simply because of their refusal to make the transition to talkies.
