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.
Silent film
Warner Bros was the first studio to accept sound as an element in film production and utilize Vitaphone, a sound-on-disc technology, to do so. The studio then released "The Jazz Singer" in 1927, which marked the first commercially successful sound film, but silent films were still the majority of features released in both 1927 and 1928, along with so-called goat-glanded films: silents with a subsection of sound film inserted. Thus the modern sound film era may be regarded as coming to dominance beginning in 1929.
