 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.
