One of the main incentives behind the 3D craze was combating illegal downloading of movies. 3D hardware is very expensive and has not yet penetrated home entertainment. The movie industry had high hopes for 3D to be some sort of "pirate-killer", because 3D cannot be pirated effectively. Alas, it seems that people prefer to download 2D rather than pay 15$ or more to watch a release in 3D.
