Steamboat Willie
"Steamboat Willie" was not the first cartoon with synchronized sound. Starting in May 1924 and continuing through September 1926, Dave and Max Fleischer's Inkwell Studios produced 19 sound cartoons, part of the "Song Car-Tunes" series, using the Phonofilm sound-on-film process. However, the "Song Car-Tunes" failed to keep the sound fully synchronized, while "Steamboat Willie" was produced using a click track to keep his musicians on the beat. As little as one month before "Steamboat Willie" was released, Paul Terry released "Dinner Time" which also used a soundtrack, but "Dinner Time" was not a financial success.
