Pixar
Pixar Animation Studios, commonly referred to as Pixar (), is an American computer animation film studio based in Emeryville, California, that is a subsidiary of Walt Disney Studios, owned by the Walt Disney Company. Pixar began in 1979 as the Graphics Group, part of the Lucasfilm computer division, before its spin-out as a corporation in 1986, with funding by Apple Inc. co-founder Steve Jobs, who became the majority shareholder. Disney purchased Pixar in 2006 at a valuation of $7.4 billion by converting each share of Pixar stock to 2.3 shares of Disney stock, a transaction that resulted in Jobs becoming Disney's largest single shareholder at the time. Pixar is best known for CGI-animated feature films created with RenderMan, Pixar's own implementation of the industry-standard RenderMan image-rendering application programming interface, used to generate high-quality images.

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".
