It used to be everywhere. James Cameron’s “Avatar” boosted the 3D market for a period of time, until it lost all steam, due to an incalculable amount of films trying to take advantage of the fad by upgrading their non-3D movies into 3D movies. I can count in a single hand the amount of movies that have come out since “Avatar” that actually benefited from the 3D treatment. Otherwise, it’s been a major studio scam whose potential hasn’t materialized as planned.
