Steamboat Willie in the context of "The Mickey Mouse Club"

The Walt Disney Company, commonly referred to as simply Disney, is an American multinational mass media and entertainment conglomerate headquartered at the Walt Disney Studios complex in Burbank, California. Founded on October 16, 1923, as an animation studio by brothers Walt Disney and Roy Oliver Disney as Disney Brothers Cartoon Studio, Disney operated under the names Walt Disney Studio and Walt Disney Productions before adopting its current name in 1986. In 1928, Disney established itself as a leader in the animation industry with the short film Steamboat Willie. The film used synchronized sound to become the first post-produced sound cartoon, and popularized Mickey Mouse, who became Disney's mascot and corporate icon.

After becoming a success by the early 1940s, Disney diversified into live-action films, television, and theme parks in the 1950s. However, following Walt Disney's death in 1966, the company's profits, especially in the animation sector, began to decline. In 1984, Disney's shareholders voted Michael Eisner as CEO, who led a reversal of the company's decline through a combination of international theme park expansion and the highly successful Disney Renaissance period of animation from 1989 to 1999. In 2005, under the new CEO Bob Iger, the company continued to expand into a major entertainment conglomerate with the acquisitions of Pixar in 2006, Marvel Entertainment in 2009, Lucasfilm in 2012, and 21st Century Fox in 2019. In 2020, Bob Chapek became the head of Disney after Iger's retirement. However, Chapek was ousted in 2022 and Iger was reinstated as CEO.

Mickey Mouse is a cartoon character co-created in 1928 by Walt Disney and Ub Iwerks. The longtime icon and mascot of the Walt Disney Company, Mickey is an anthropomorphic mouse who typically wears red shorts, large shoes, and white gloves. He is often depicted with a cast of characters including his girlfriend Minnie Mouse, his pet dog Pluto, his best friends Donald Duck and Goofy, and his nemesis Pete.

Mickey was created as a replacement for a prior Disney character, Oswald the Lucky Rabbit. The character was originally to be named "Mortimer Mouse", until Disney's wife, Lillian, suggested "Mickey". Mickey first appeared in two 1928 shorts Plane Crazy and The Gallopin' Gaucho (which were not picked up for distribution) before his public debut in Steamboat Willie (1928). The character went on to appear in over 130 films, mostly shorts as well as features such as Fantasia (1940). Since 1930, Mickey has been featured extensively in comic strips (including the Mickey Mouse comic strip, which ran for 45 years) and comic books (such as Mickey Mouse). The character has also been featured in television series such as The Mickey Mouse Club (1955–1996).

Plane Crazy is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. The cartoon, released by Walt Disney Animation Studios, is the first finished project to feature appearances of Mickey Mouse and Minnie Mouse, and was originally a silent film. It was given a test screening to a theater audience and potential distributors on May 15, 1928. An executive from Metro-Goldwyn-Mayer saw the film, but the film failed to pick up a distributor. Later that year, Disney released Mickey's first sound cartoon, Steamboat Willie, which was an enormous success; Plane Crazy was officially released as a sound cartoon on March 17, 1929. It was the fourth Mickey film to be given a wide release after Steamboat Willie, as well as The Gallopin' Gaucho and The Barn Dance (1929).

The Gallopin' Gaucho is a 1928 American animated short film and the second short film featuring Mickey Mouse to be produced, following Plane Crazy and preceding Steamboat Willie. The Disney studios completed the silent version in August 1928, but did not release it in order to work on Steamboat Willie. The Gallopin' Gaucho was released, with sound, after Steamboat Willie on December 30 of the same year.

Both Mickey and Minnie Mouse had already made their initial debuts with the test screening of Plane Crazy on May 15, 1928, but that film had failed to catch the attention of distributors when first produced as a silent film. The Gallopin' Gaucho was a second attempt at success by co-directors Walt Disney and Ub Iwerks. The latter also served as the sole animator for it.

Walt Disney Animation Studios (WDAS), sometimes shortened to Disney Animation, is an American animation studio which produces animated feature films and short films for the Walt Disney Company. The studio's current production logo features a scene from its first synchronized sound cartoon, Steamboat Willie (1928). Founded on October 16, 1923, by brothers Walt and Roy O. Disney after the closure of Laugh-O-Gram Studio, it is the longest-running animation studio in the world. It is currently organized as a division of Walt Disney Studios and is headquartered at the Roy E. Disney Animation Building at the Walt Disney Studios lot in Burbank, California. Since its foundation, the studio has produced 64 feature films, from Snow White and the Seven Dwarfs (1937)—which is also the first hand-drawn animated feature film—to Zootopia 2 (2025), and hundreds of short films.

Founded as Disney Brothers Cartoon Studio (DBCS) in 1923, renamed Walt Disney Studio (WDS) in 1926 and incorporated as Walt Disney Productions (WDP) in 1929, the studio was dedicated to producing short films until it entered feature production in 1934, resulting in 1937's Snow White and the Seven Dwarfs, one of the first full-length animated feature films and the first U.S.-based one. In 1986, during a large corporate restructuring, Walt Disney Productions, which had grown from a single animation studio into an international media conglomerate, was renamed the Walt Disney Company and the animation studio became Walt Disney Feature Animation (WDFA) in order to differentiate it from the company's other divisions. Its current name was adopted in 2006 after Pixar Animation Studios was acquired by Disney.

Dinner Time (1928) is an American animated short subject produced by Amadee J. Van Beuren, directed by Paul Terry, co-directed by John Foster, and produced at Van Beuren Studios. Josiah Zuro arranged and conducted the "synchronized" music score. The film is part of a series entitled Aesop's Fables and features the Terry creation Farmer Al Falfa who works as a butcher, fending off a group of pesky dogs.

Dinner Time was one of the first publicly shown sound-on-film cartoons. It premiered at the Strand Theater New York City in August 1928 and was released by Pathé Exchange on October 14, a month before Walt Disney's sound cartoon, Steamboat Willie. Dinner Time was not successful with audiences and Disney's film would be widely touted as the first synchronized sound cartoon.

Mickey Mouse (originally known as Mickey Mouse Cartoons) is a series of American animated comedy short films produced by Walt Disney Productions. The series started in 1928 with Steamboat Willie and ended with 2013’s Get a Horse! being the last in the series to date, otherwise taking a hiatus from 1953 to 1983. The series is notable for its innovation with sound synchronization and character animation, and also introduced well-known characters such as the titular protagonist Mickey Mouse, Minnie Mouse, Pluto and Goofy.

The name "Mickey Mouse" was first used in the films' title sequences to refer specifically to the character, but was used from 1935 to 1953 to refer to the series itself, as in "Walt Disney presents a Mickey Mouse". In this sense "Mickey Mouse" was a shortened form of "a Mickey Mouse cartoon" which was used in the earliest films. Films from 1929 to 1935 which were re-released during this time also used this naming convention, but it was not used for the three shorts released between 1983 and 1995 (Mickey's Christmas Carol, The Prince and the Pauper, and Runaway Brain). Mickey's name was also used occasionally to market other films which were formally part of other series. Examples of this include several Silly Symphonies and Goofy and Wilbur (1939).
