Walt Disney Animation Studios (WDAS | sometimes shortened to Disney Animation) is an American animation studio that creates animated features and short films for The Walt Disney Company. Founded on October 16, 1923, by brothers Walt Disney and Roy O. Disney, it is one of the oldest-running animation studios in the world. It is currently organized as a division of Disney Studios Content and is headquartered at the Roy E. Disney Animation Building at the Walt Disney Studios lot in Burbank, California. Since its foundation, the studio has produced 58 feature films, from Snow White and the Seven Dwarfs (1937) to Frozen II (2019), and hundreds of short films. Founded as Disney Brothers Cartoon Studio in 1923, renamed Walt Disney Studio in 1926, and incorporated as Walt Disney Productions in 1929, the studio was exclusively dedicated to producing short films until it expanded into feature production in 1934, resulting in 1937's Snow White and the Seven Dwarfs, one of the first full-length animated feature films and the first one made in the United States. In 1986, during a significant corporate restructuring, Walt Disney Productions, which had grown from a single animation studio into an international multimedia company, was renamed The Walt Disney Company and the animation studio Walt Disney Feature Animation to differentiate it from the other divisions. Its current name was adopted in 2007 after Disney acquired Pixar Animation Studios in the previous year. For much of its existence, the studio was recognized as the premier American animation studio; it developed many techniques, concepts, and principles that became standard practices of traditional animation. The studio also pioneered the art of storyboarding, which is now a standard technique used in both animated and live-action filmmaking. The studio's catalog of animated features is among Disney's most notable assets, with the stars of its animated shorts – Mickey Mouse, Minnie Mouse, Donald Duck, Daisy Duck, Goofy, and Pluto – becoming recognizable figures in popular culture and mascots for The Walt Disney Company as a whole. Walt Disney Animation Studios is currently managed by Jennifer Lee (Chief Creative Officer) and Clark Spencer (President) and continues to produce films using both traditional animation and computer-generated imagery (CGI).
