The Jazz Singer in the context of "Saint Louis Park, Minnesota"

A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures became 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. Before sound-on-film technology became viable, soundtracks for films were commonly played live with organs or pianos.

The primary steps in the commercialization of sound cinema were taken in the mid-to-late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie (although it had only limited sound sequences) was The Jazz Singer, which premiered on October 6, 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.

Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by the Walt Disney Studio and was released by Pat Powers, under the name of Celebrity Productions. The cartoon is considered the public debut of Mickey Mouse and Minnie Mouse, although both appeared months earlier in a test screening of Plane Crazy and the then unreleased The Gallopin' Gaucho. Steamboat Willie is the third of Mickey's films to have been produced, but it is the first to have been distributed, because Disney had seen The Jazz Singer (1927) and became determined to produce one of the first fully synchronized sound cartoons.

Steamboat Willie is one of the first cartoons with synchronized sound, and one of the first cartoons to feature a fully post-produced soundtrack, which distinguished it from earlier sound cartoons, such as Inkwell Studios's Song Car-Tunes (1924–1926), My Old Kentucky Home (1926), and Van Beuren Studios's Dinner Time (1928). Disney believed that synchronized sound was the future of film.

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 is the last major analog sound-on-disc system and the only one that was widely used and commercially successful. The soundtrack is not printed on the film, but issued separately on phonograph records. The discs, recorded at 33+1⁄3 rpm (a speed first used for this system) and typically 16 inches (41 cm) in diameter, are played on a turntable physically coupled to the projector motor while the film is projected. Its frequency response is 4300 Hz. 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".

The "Vitaphone" trademark was later associated with cartoons and other short subjects that had optical soundtracks and did not use discs.

Samuel Louis Warner (born Szmuel Wonsal, August 10, 1887 – October 5, 1927) was an American film producer who was the co-founder and chief executive officer of Warner Bros. He established the studio along with his brothers Harry, Albert, and Jack L. Warner. Sam Warner is credited with procuring the technology that enabled Warner Bros. to produce the film industry's first feature-length talking picture, The Jazz Singer. He died in 1927, on the day before the film's enormously successful premiere.

Jack Leonard Warner (born Jacob Warner; August 2, 1892 – September 9, 1978) was a Canadian-born American film executive, who was the president and driving force behind the Warner Bros. Studios in Burbank, California. Warner's career spanned over 55 years, surpassing that of any other of the pioneering Hollywood studio moguls.

As co-head of production at Warner Bros. Studios, Warner worked with his brother, Sam Warner, to procure the technology for the film industry's first talking picture, The Jazz Singer (1927). After Sam's death, Jack clashed with his surviving older brothers, Harry and Albert Warner. He assumed exclusive control of the company in the 1950s when he secretly purchased his brothers's shares in the business after convincing them to participate in a joint sale of stocks.

The Jazz Fool is a Mickey Mouse short animated film first released on October 15, 1929, as part of the Mickey Mouse film series. It was the twelfth Mickey Mouse short to be produced, the ninth of that year.

The cartoon's title combines the titles of two Al Jolson films: The Jazz Singer (1927) and The Singing Fool (1928). An early version of Horace Horsecollar appears, but is not yet the anthropomorphized character that he later evolves into.
