Blue Sky Studios

Blue Sky Studios is an American computer animation film studio based in Greenwich, Connecticut. Founded in 1987 by the visual effects team behind Tron, it is owned since 1997 by 20th Century Fox. Using its in-house rendering software, the studio had worked on visual effects for commercials and films, before releasing in 2002 its first animated film, Ice Age, and completely dedicated to producing animated films. The studio has produced eight animated films, with Ice Age and Rio being the most successful franchises.

Matt Groening, the creator of The Simpsons, said that the company was going to make Kirby 4ever: A Bigger and Longer Adventure! (since Fox owns both Blue Sky and the Kirby 4ever movies), respectively. But Kirby4ever said it was actually 4ever Entertainment who would be doing it.
