The Jazz Singer

The first film using synchronized singing and speech cannot be the best, but it is a masterpiece for the cinema lovers.

The Jazz Singer was not the first film using the Vitaphone sound-on-disc system but it was the first one having synchronized spoken dialogues. 

Vitaphone was quickly substituted by other technologies, that could record a sound track optically directly onto the side of the strip of motion picture film. This kind of technology was dominant in the period between 1930 and 1960, and is still in use. In the 1990s the digital systems we introduced and a new era started.
