The studio's predecessor (and the modern-day The Walt Disney Company's as a whole) was founded as the Disney Brothers Cartoon Studio, by filmmaker Walt Disney and his business partner and brother, Roy, in 1923.
The creation of Mickey Mouse and subsequent short films and merchandise generated revenue for the studio which was renamed as The Walt Disney Studio at the Hyperion Studio in 1926. In 1929, it was renamed again to Walt Disney Productions. The studio's streak of success continued in the 1930s, culminating with the 1937 release of the first feature-length animated film, Snow White and the Seven Dwarfs, which becomes a huge financial success. With the profits from Snow White, Walt relocated to a third studio in Burbank, California.
In the 1940s, Disney began experimenting with full-length live-action films, with the introduction of hybrid live action-animated films such as The Reluctant Dragon (1941) and Song of the South (1946). That same decade, the studio began producing nature documentaries with the release of Seal Island (1948), the first of the True-Life Adventures series and a subsequent Academy Award winner for Best Live-Action Short Film.
