The BBC's Imagine arts show tonight takes a look at animated feature films, and the sea-change in that part of the industry introduced by the release of Pixar's Toy Story in 1995.
Presenter Alan Yentob will "look at the new golden age of animation in the show (From pencils to Pixels), which broadcasts at 10.35pm.
It aims to show how technology has changed the way animated movies are made. In 1911, when the first such movies appeared, work was done by hand.
The introduction of computer-generated animation has changed the industry. "Imagine talks to the people at the heart of the industry to try and find out whether this really is the end for traditional animation techniques," says the BBC.
Yentob will talk with Toy Story creator John Lasseter, veteran animators Frank Thomas and Ollie Johnston and Aardman Animations' Nick Park.
