Disney

The transition from the American Midwest to California marked the formal beginning of the enterprise. Following the financial collapse of Laugh-O-Gram Studio in Kansas City, Walt Disney arrived in Los Angeles in 1923 with a partial film reel and limited capital. He joined his brother, Roy O. Disney, to seek distribution for a hybrid live-action and animated concept.

New York distributor Margaret J. Winkler agreed to fund a series based on this pilot, titled the Alice Comedies. On October 16, 1923, the brothers established the Disney Brothers Cartoon Studio to fulfill this contract. The production involved filming a live child actress, Virginia Davis, against animated backgrounds.

Success with the Alice series led to a relocation to Hyperion Avenue in January 1926, where the firm was renamed Walt Disney Studio. By 1927, the market demand for purely animated content prompted the creation of Oswald the Lucky Rabbit. This character was developed for Universal Pictures through Charles Mintz, who had assumed control of Winkler’s distribution business.

A contractual impasse in 1928 fundamentally altered the studio's trajectory. Mintz attempted to reduce production fees while revealing that Universal Pictures held the legal rights to the Oswald character. Most of the studio's animation staff departed to work directly for Mintz, leaving only Ub Iwerks in collaboration with the brothers.

In response to the loss of their primary intellectual property, the studio developed a new protagonist. Mickey Mouse appeared in two silent test screenings, Plane Crazy and The Gallopin' Gaucho, during the spring of 1928. These initial efforts failed to secure a distributor until the introduction of synchronized sound.

The premiere of Steamboat Willie on November 18, 1928, at the Colony Theatre in New York established a new technical standard. By integrating a fully post-produced soundtrack, the film achieved significant public recognition. This success allowed the brothers to maintain independent control over their future productions and intellectual property.
