Pixar Animation Studios is an American computer animation film studio based in Emeryville, California, United States. The studio has earned twenty-six Academy Awards, seven Golden Globes, and three Grammys, among many other awards and acknowledgments. Its films have made over $6.3 billion worldwide. It is best known for its CGI-animated feature films created with PhotoRealistic RenderMan, its own implementation of the industry-standard RenderMan image-rendering application programming interface used to generate high-quality images. Pixar began in 1979 as the Graphics Group, part of the Computer Division of Lucasfilm before it was acquired by Apple co-founder Steve Jobs in 1986. The Walt Disney Company bought Pixar in 2006 at a valuation of $7.4 billion; the transaction made Jobs the largest shareholder in Disney. Pixar has produced eleven feature films, beginning with Toy Story in 1995.
