Earlier today I reported on the unlikelihood that the next Batman movie will be in 3D. But is that a fluke or part of a trend? If box office numbers are any indication, it's definitely the latter.

Since the high-water mark of Avatar, where 71% of the revenue came from 3D screenings, numbers for big-budget 3D movies have plummeted to less than 50%.

Obviously Avatar was a unique case in that it was basically sold as a 3D "experience," so if you saw it in 2D you were missing out. But then three months later the animated How to Train Your Dragon pulled in 68% of its revenue from 3D screens, hardly a significant drop-off.
