The "Technojunkies" and "Gotta have it first" already have it and the rest just can't either be bothered or just don't find any appeal to it.
3D offerings on Cable/Sat are few and far between and the Movies generally fall into the following catagories Junk, Garbage, Something far Worse or Children's Annimation.
