Pixar Studios

Pixar Animation Studios was one of the first companies/studios to rise in the film industry. Pixar was purchased by Steven Jobs, the head of Apple Computer, and the company was named Pixar after its Pixar computer. Pixar was given many awards for its computer animation softwares including RenderMan, Marionette, and Ringmaster. The company made several commercials for other companies, but then collaborated with Disney to make computer-animated films such as Toy Story, Toy Story 2, A Bug's Life, and other films. More recently, Pixar and Disney have made Ratatouille, Wall-E, Up, and Toy Story 3. In partnership with each other, Pixar and Disney have proceeded to dominate the animated-film sector of the film industry.
