Pixar knows as Pixar Animation Studios... have published a lot of titles and is now 24!
Tin Toy, Cars, Ratatouille, Incredibles, finding nemo, monster Inc, Bugs Life.... Toy Story, Wall E, Up ! A long story and a lot of work and research (I think to the paper library ... here. So many people ignore publish research papers and make it accessible to public).
For the small story :
Pixar was created in 1979 as the Graphics Group, a service of the Lucasfilm Computer Division (computer division of Lucasfilm) before being bought by Apple cofounder Steve Jobs, in 1986. The Walt Disney Company bought Pixar in 2006.
So Steve Jobs have changed the world also by allowing a great company to make great film... and not only by making usable and polish designed products (knows as Mac, Ipod, Ipad)...
