The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures were made commercially practical. Reliable synchronization was difficult to achieve with the early sound-on-disc systems, and amplification and recording quality were also inadequate. Innovations in sound-on-film led to the first commercial screening of short motion pictures using the technology, which took place in 1923.  - Vitaphone was a sound film system used for feature films and nearly 1,000 short subjects made by Warner Bros. and its sister studio First National from 1926 to 1931. Vitaphone was the last major analog sound-on-disc system and the only one which was widely used and commercially successful. The soundtrack was not printed on the film itself, but issued separately on phonograph records. The discs, recorded at  rpm (a speed first used for this system) and typically in diameter, would be played on a turntable physically coupled to the projector motor while the film was being projected. Many early talkies, such as "The Jazz Singer" (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound".  - Smiling Irish Eyes ( 1929 ) is a sound ( All - Talking ) American musical film with Technicolor sequences .
