How is Toy Story an important piece of film history?

Toy Story was the first feature length, computer-animated film in history. With the combined talents of both Walt Disney Studios and Pixar Animation, Lasseter and Disney created a film that would change the world of animation forever. Today, many more movies have been created entirely by computer animation. However, few eclipse the pioneering Toy Story, which used computers to build an imaginative world in which toys are the main characters and have complex feelings and lives, just like humans.
