- Warner Bros. film was successful and placed pressure on other studios to change to talkies; and
- The film has a tendency to be falsely consider the 'historic moment' of when sound in film was invented.
The sound in Jazz Singer was predominantly made up of singing with only a few sequences of synchronised dialogue and produced on vitaphone sound-on-disc system. While the film extended on the use of sound in Don Juan, but sound was still at an infantile stage. However, the success of the film enourage the major studio who were Paramount, Lowes and First National to follow Warner Bros. By 1928, the sound on disc was replaced with sound being photographed straight on to the film.
A little trivia: the sound was processed on the left hand side of the film.
