Mickey Mouse
Created as a replacement for a prior Disney character, Oswald the Lucky Rabbit, Mickey first appeared in the short "Plane Crazy", debuting publicly in the short film "Steamboat Willie" (1928), one of the first sound cartoons. He went on to appear in over 130 films, including "The Band Concert" (1935), "Brave Little Tailor" (1938), and "Fantasia" (1940). Mickey appeared primarily in short films, but also occasionally in feature-length films. Ten of Mickey's cartoons were nominated for the Academy Award for Best Animated Short Film, one of which, "Lend a Paw", won the award in 1942. In 1978, Mickey became the first cartoon character to have a star on the Hollywood Walk of Fame.
Mickey Mouse universe
The Mickey Mouse universe essentially originated with the debut of Mickey himself in 1928. Although Mickey's stories included the character Pete, who was created in 1925, the world in which Mickey lives holds a continuity largely independent from earlier films. An exception to this was the reintroduction of Oswald the Lucky Rabbit in 2010 with the release of "Epic Mickey".
