In October 1954, the ABC network launched Disney's first regular television series, Disneyland, which would go on to become one of the longest-running primetime series in history.Disneyland allowed Disney a platform to introduce new projects and broadcast older ones, and ABC became Disney's partner in the financing and development of Disney's next venture, located in the middle of an orange grove near Anaheim, California.When the United States entered the war after the attack on Pearl Harbor, many of Disney's animators were drafted into the armed forces. By 1942, 90% of its 550 employees were working on war-related films.Films such as the feature Victory Through Air Power and the short Education for Death (both 1943) were meant to increase public support for the war effort.
With limited staff and little operating capital during and after the war, Disney's feature films during much of the 1940s were "package films", or collections of shorts, such as The Three Caballeros (1944) and Melody Time (1948), which performed poorly at the box-office.
Disney released cartoons through Powers' Celebrity Pictures (1928–1930), Columbia Pictures (1930–1932), and United Artists (1932–1937).
Deciding to push the boundaries of animation even further, Disney began production of his first feature-length animated film in 1934.
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.
and began the Silly Symphony series with Columbia Pictures signing on as Symphonies distributor in August 1929.
