Mickey Mouse is an anthropomorphic mouse created by Walt Disney and Ub Iwerks in 1928. He is the official mascot of The Walt Disney Company. Mickey first appeared in the test screening of the short film Plane Crazy and made his official debut in Steamboat Willie, one of the first sound cartoons. Mickey went on to star in over 130 films and shorts. He became the first cartoon character to receive a star on the Hollywood Walk of Fame in 1978. Mickey has been extensively featured in comic strips, comic books, television shows, and merchandise throughout the decades. Originally characterized as mischievous, his popularity led to him being rebranded as more of an everyman hero.
