Classical Hollywood cinema
The beginning of the sound era itself is ambiguously defined. To some, it began with "The Jazz Singer", which was released in 1927 and increased box-office profits for films, as sound was introduced to feature films. To others, the era began in 1929, when the silent age had definitively ended. Most Hollywood pictures from the late 1920s to 1960s adhered closely to a genre—Western, slapstick comedy, musical, animated cartoon, and biopic (biographical picture)—and the same creative teams often worked on films made by the same studio. For instance, Cedric Gibbons and Herbert Stothart always worked on MGM films; Alfred Newman worked at Twentieth Century Fox for twenty years; Cecil B. DeMille's films were almost all made at Paramount Pictures; and director Henry King's films were mostly made for Twentieth Century Fox. Similarly, actors were mostly contract players. Film historians and critics note that it took about a decade for films to adapt to sound and return to the level of artistic quality of the silents, which it did in the late 1930s.
The Dickson Experimental Sound Film
The Dickson Experimental Sound Film is a film made by William Dickson in late 1894 or early 1895. It is the first known film with live-recorded sound and appears to be the first motion picture made for the Kinetophone, the proto-sound-film system developed by Dickson and Thomas Edison. (The Kinetophone, consisting of a Kinetoscope accompanied by a cylinder-playing phonograph, was not a true sound-film system, for there was no attempt to synchronize picture and sound throughout playback.) The film was produced at the "Black Maria", Edison's New Jersey film studio. There is no evidence that it was ever exhibited in its original format. Newly digitized and restored, it is the only surviving Kinetophone film with live-recorded sound.
