Mickey Mouse was invented by Walt Disney and his wife, Lillian, although some claim that Mickey Rooney was the inspiration behind the mouse. Regardless of who inspired the mouse, Disney initially dubbed the animated character Mortimer, but that name was later changed to Mickey Mouse.
Mickey Mouse has become a popular character in American culture since he was created and his first hit short film, "Steamboat Willie," hit audiences. The short premiered in 1928 and was a huge commercial hit due to its ability to synchronize audio with the film. Mickey Mouse even received a star on the famous Hollywood Walk of Fame in 1978 after 50 years of being a fan favorite character. He was the first animated character to secure a spot.
