Minnie Mouse in the context of "Mickey Mouse (TV series)"

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).

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.

The Mickey Mouse universe is a fictional shared universe which is the setting for stories involving Disney cartoon characters, including Mickey and Minnie Mouse, Donald and Daisy Duck, Goofy and Pluto as the primary members (colloquially known as the "Sensational Six"), and many other characters related to them, most of them being anthropomorphic animals. The universe originated from the Mickey Mouse animated short films produced by Disney starting in 1928, although its first consistent version was created by Floyd Gottfredson in the Mickey Mouse newspaper comic strip. Real-world versions also exist in Disneyland and Tokyo Disneyland, called Mickey's Toontown. The term "Mickey Mouse universe" is not officially used by The Walt Disney Company, but it has been used by Disney comics author and animation historian David Gerstein. The Walt Disney Company typically uses terms such as Mickey & Friends or Mickey & the Gang to refer to the character franchise.

Since 1990, the city in which Mickey lives is typically called Mouseton in American comics. In modern continuity, Mouseton is often depicted as being located in the fictional U.S. state of Calisota, analogous to Northern California. This fictional state was invented by comics writer Carl Barks in 1952 as the location for Donald Duck's home city, Duckburg.

Pluto is an American cartoon character created by Walt Disney and Norm Ferguson. He is a yellow-orange color, medium-sized, short-haired dog with black ears. Unlike most Disney characters, Pluto is not anthropomorphic beyond some characteristics such as facial expression. He is Mickey Mouse's pet. Officially a mixed-breed dog, he made his debut as a bloodhound in the Mickey Mouse cartoon The Chain Gang. Together with Mickey Mouse, Minnie Mouse, Donald Duck, Daisy Duck, and Goofy, Pluto is one of the "Sensational Six"—the biggest stars in the Disney universe. Though all six are non-human animals, Pluto alone is not dressed as a human.

Pluto debuted in animated cartoons and appeared in 24 Mickey Mouse films before receiving his own series in 1937. All together Pluto appeared in 89 short films between 1930 and 1953. Several of these were nominated for an Academy Award, including The Pointer (1939), Squatter's Rights (1946), Pluto's Blue Note (1947), and Mickey and the Seal (1948). One film starring him, Lend a Paw (1941), won the award in 1942. Because Pluto does not speak, his presence relies on physical humor. This made him a pioneering figure in character animation, by expressing personality through animation rather than dialogue.

Pete (also named Peg Leg Pete, Bad Pete, and Black Pete, among other names) is a cartoon character created by Walt Disney and Ub Iwerks of The Walt Disney Company. Pete is traditionally depicted as the villainous arch-nemesis of Mickey Mouse, and was made notorious for his repeated attempts to kidnap Minnie Mouse. Pete is the oldest continuing Disney character, having debuted in the cartoon Alice Solves the Puzzle in 1925. He originally bore the appearance of an anthropomorphic bear, but with the advent of Mickey in 1928, he was defined as a cat.

Pete appeared in 67 animated short films between 1925 and 1954, having been featured in the Alice Comedies and Oswald the Lucky Rabbit cartoons, and later in the Mickey Mouse, Donald Duck, and Goofy cartoons. During World War II, he played the long-suffering sergeant trying to make a soldier out of Donald Duck in a series of animated shorts.

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.

Mickey Mouse (briefly Mickey Mouse and Friends) is a Disney comic book series that has a long-running history, first appearing in 1943 as part of the Four Color one-shot series. It received its own numbering system with issue #28 (December 1952).

The book emphasizes stories with Mickey and his supporting cast: Goofy, Donald Duck, Minnie Mouse, Pluto and Mickey's nephews Morty and Ferdie Fieldmouse. Mickey's perpetual rival is the criminal Peg-Leg Pete (sometimes "Black Pete", "Sneaky Pete" or "Big Bad Pete"). Other adversaries have included Emil Eagle, Eli Squinch, Sylvester Shyster, the team of Dangerous Dan McBoo and Idjit the Midget, and the Phantom Blot. Two major artistic influences on the appearance of Mickey in comics are Floyd Gottfredson, who drew the Mickey Mouse comic strip from 1930 to 1975, and comic book artist Paul Murry, who drew Mickey stories from 1950 to 1984.

The golden age of American animation was a period that began with the popularization of sound synchronized cartoons in 1928, and gradually ended throughout in the early-1960s when theatrical animated cartoon film shorts started to lose popularity to the newer medium of television. Animated media from after the golden age, especially on television, were produced on cheaper budgets and with more limited techniques between in the late-1950s and in the mid-1980s.

Multiple highly-popular animated cartoon characters emerged from this period, including:
