The Walt Disney Company
In 1928, to recover from the loss of Oswald the Lucky Rabbit, Disney came up with the idea of a mouse character named Mortimer while on a train headed to California, drawing up a few simple drawings. The mouse was later renamed Mickey Mouse (Disney's wife, Lillian, disliked the sound of 'Mortimer Mouse') and starred in several Disney produced films. Ub Iwerks refined Disney's initial design of Mickey Mouse. Disney's first sound film "Steamboat Willie", a cartoon starring Mickey, was released on November 18, 1928 through Pat Powers' distribution company. It was the first Mickey Mouse sound cartoon released, but the third to be created, behind "Plane Crazy" and "The Gallopin' Gaucho". "Steamboat Willie" was an immediate smash hit, and its initial success was attributed not just to Mickey's appeal as a character, but to the fact that it was the first cartoon to feature synchronized sound. Disney used Pat Powers' Cinephone system, created by Powers using Lee de Forest's Phonofilm system. "Steamboat Willie" premiered at B. S. Moss's Colony Theater in New York City, now The Broadway Theatre. Disney's "Plane Crazy" and "The Gallopin' Gaucho" were then retrofitted with synchronized sound tracks and re-released successfully in 1929.
Goofy
Goofy first appeared in "Mickey's Revue", first released on May 25, 1932. Directed by Wilfred Jackson this short movie features Mickey Mouse, Minnie Mouse, Horace Horsecollar and Clarabelle Cow performing another song and dance show. Mickey and his gang's animated shorts by this point routinely featured song and dance numbers. It begins as a typical Mickey cartoon of the time, but what would set this short apart from all that had come before was the appearance of a new character, whose behavior served as a running gag. Dippy Dawg, as he was named by Disney artists (Frank Webb), was a member of the audience. He constantly irritated his fellow spectators by noisily crunching peanuts and laughing loudly, till two of those fellow spectators knocked him out with their mallets (and then did the same exact laugh as he did). This early version of Goofy had other differences with the later and more developed ones besides the name. He was an old man with a white beard, a puffy tail and no trousers, shorts, or undergarments. But the short introduced Goofy's distinct laughter. This laughter was provided by Pinto Colvig. A considerably younger Dippy Dawg then appeared in "The Whoopee Party", first released on September 17, 1932, as a party guest and a friend of Mickey and his gang. Dippy Dawg made a total of four appearances in 1932 and two more in 1933, but most of them were mere cameos.
