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.
Lights of New York (1928 film)
Lights of New York is a 1928 American crime drama film starring Helene Costello, Cullen Landis and Eugene Pallette, and directed by Bryan Foy. Filmed in the Vitaphone sound-on-disc sound system, it is the first all-talking full-length feature film, released by Warner Bros., who had introduced the first feature-length film with synchronized sound "Don Juan (1926 film)" two years earlier. The film, which cost $23,000 to produce ("B" picture), grossed over $1,000,000. The enthusiasm with which audiences greeted the talkies was so great that by the end of 1929, Hollywood was producing sound films exclusively.
