List of animation studios owned by The Walt Disney Company
Pixar () is an American computer animation film studio based in Emeryville, California. The studio is best known for its CGI-animated feature films created with PhotoRealistic RenderMan, its own implementation of the industry-standard RenderMan image-rendering application programming interface used to generate high-quality images. Pixar began in 1979 as the Graphics Group, part of the computer division of Lucasfilm before its spin-out as a corporation in 1986 with funding by Apple Inc. co-founder Steve Jobs, who became its majority shareholder. Pixar and Disney had a seven feature agreement that allowed Disney to distribute the films with Disney owing the character rights. With the success of "Toy Story 2" in 1999, then-Disney CEO Michael Eisner and Pixar CEO Steve Jobs began to disagree on how Pixar should be run and the terms of their continued relationship. Eisner claimed that Toy Story 2 would not count towards the "original" film count of the agreement. Jobs announced in January 2004 that Pixar would not renew their agreement with Disney and would seek out other distributors for releases starting in 2006. In 2004, Disney Circle 7 Animation was formed as a CG animation studio to create sequels to the Disney-owned Pixar properties. In Late January 2006, new Disney CEO Bob Iger and Jobs agreed to have Disney purchase Pixar which led to Disney closing Circle 7.
Ralph Guggenheim
After his time at CMU, Ralph worked for the New York Institute of Technology Computer Graphics Lab. He was soon contacted by Lucasfilm and moved to California in 1980. During his time at Lucasfilm, Guggenheim developed EditDroid, which proved to be a revolutionary film-editing system. After his research lab at Lucasfilm was sold to Steve Jobs and renamed Pixar, Guggenheim continued to work in the world of graphics and animation. Guggenheim, a respected founder of Pixar, eventually became Vice President of Feature Animation and was a lead producer for "Toy Story." Guggenheim left the company in 1997 after Disney forced Pixar to remove him as producer from "Toy Story 2".
