In which year was the first film with the synchronized sound made?

The 1927 film, "The Jazz Singer", marked the first feature-length movie with synchronized dialogue that initiated the dawn of Talkies and ended the silent-film era.

Warner Brothers, which in the late 1920s was a small upcoming studio acquired a sound-on-disc system called Vitaphone. It was first used in 1926 with Don Juan, a lavish costume drama featuring a score performed by the New York Philharmonic Orchestra. Next came the American Musical, "The Jazz Singer", the second Vitaphone feature, but the first full feature film to have a soundtrack with the inclusion of dialogue.

The film’s financial success laid strong foundations for Warner Brothers as a major studio, and it won an honorary Academy Award at the first Oscars in 1929, for “producing The Jazz Singer, the pioneer outstanding talking picture, which has revolutionized the industry.”

There have been many remakes of the story onscreen and onstage, but nonetheless, the film has been strongly criticized for Jolson’s performance in blackface as it stereotypes characterization and the problems of assimilation often encountered by ethnic(African-American) groups.
