At the start of the 2000s, traditionally animated feature-films were starting to fall from favor from audiences as a result of the increasing successes of computer-animated CG movies. In 2000, Fox Animation Studios closed down due to the box office failure of "Titan A.E." which cost between $75 and $90 million, but only earned $38.8 million worldwide. As a result, Fox cut ties with Don Bluth and Gary Goldman, and moved animation services to Blue Sky Studios, where they worked on their first feature, "Ice Age" in 2002.
