Walt Disney Feature Animation (WDFA) is the animation studio that makes up a key element of The Walt Disney Company. The Feature Animation studio was an integrated part of Walt Disney Productions from 1934 (the start of production on Snow White and the Seven Dwarfs) until 1986, when, during the corporate restructuring to create The Walt Disney Company, it officially became a subsidiary of the company.
Pixar Animation Studios is an award-winning American computer animation studio based in Emeryville, California (USA). It is a division of The Walt Disney Company.
Though best known for its production of computer-animated feature films, Pixar also develops and markets high-end 3D computer graphics technology. Most notably, Pixar is the developer of the industry-standard rendering software RenderMan, which is used to generate high-quality, photorealistic images.
On January 24, 2006, The Walt Disney Company agreed to buy Pixar for $7.4 billion through an all-stock transaction. The acquisition was completed on May 5, 2006 (swapping one Pixar share for 2.3 shares of Disney), making Pixar a wholly-owned subsidiary of Disney.
