The first project the Disney brothers worked on was a series entitled Alice’s Wonderland, and in 1925, Walt Disney convinced his brother to rename the studio to Walt Disney Studios. After several smaller successes and failures, the first Mickey Mouse cartoons Plane Crazy and Steamboat Willie were released to audiences in 1928. As it was the first cartoon with sound to achieve popularity, Walt Disney was able to expand his ventures a year later into three additional companies: Walt Disney Enterprises, Disney Film Recording Company, and Liled Realty and Investment Company.
Over the next several years, what would become some of Disney’s most beloved characters were introduced: Pluto in 1930, Goofy in 1932, and Donald Duck in 1934. It was in 1937 that the studio’s first feature-length animation film was released, Snow White and the Seven Dwarfs, and it made history books by being the first animated feature film ever produced. The next year, Walt Disney merged all of his companies under one title, Walt Disney Productions, and in 1940 the production house released both Pinocchio and Fantasia.
