Per the Nikkster:
[According to SNL Kagan,] average revenues for the decade’s 101 animated films ran 108.4% ahead of costs. DreamWorks Animation’s Shrek 2 led the category with a 462% margin. The 71 sci-fi/fantasy films had a margin of 108.1%. Fox’s Avatar is the winner here with revenues 554% ahead of costs. ...
Sort of explains why fantasy and sci fi features, heavy with CG effects, get made so often. And why CG animated features are being produced by every major conglomerate. They are just too large a profit center to ignore.
But if you've been awake and paying attention during the past, oh, twenty years, you undoubtedly know this. We're a loong way from the sleepy days of Fox and the Hound, Pagemaster and Once Upon a Forest. And we're a long way from Saturday morning kiddie cartoons.
Computers and their spawn have turned the industry upside down and inside out, and made animation a high margin* part of moviedom.
* We're speaking here in relative terms.
