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.
John Lasseter
Due to George Lucas's financially crippling divorce, he was forced to sell off Lucasfilm Computer Graphics, by this time renamed the Pixar Graphics Group, founded by Smith and Catmull, with Lasseter as one of the founding employees. It was spun off as a separate corporation with Steve Jobs as its majority shareholder in 1986. Over the next 10 years, Pixar evolved from a computer company that did animation work on the side into an animation studio. Lasseter oversaw all of Pixar's films and associated projects as executive producer. As well as "Toy Story", he also personally directed "A Bug's Life" (1998), "Toy Story 2" (1999), "Cars" (2006), and "Cars 2" (2011).
