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.
Walt Disney Animation Studios
It was founded as the Disney Brothers Cartoon Studio in 1923 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. In 1983, Walt Disney Productions named its live action film studio Walt Disney Pictures. During a corporate restructuring in 1986, Walt Disney Productions was renamed The Walt Disney Company and the animation division, renamed Walt Disney Feature Animation, became a subsidiary of its film division, The Walt Disney Studios. In 2007, Walt Disney Feature Animation took on its current name, Walt Disney Animation Studios after Pixar was acquired by Disney in the same year.
