Or so says a published Tuesday by the and the on consumer interest in stereoscopic 3D technology, in which each eye is presented with a different picture.

Surveying 1,002 American adults in December, the report's authors found that interest increases as more movies are shown theatrically in 3D. People who see 3D movies in theaters want to see more of them, both in theaters and at home.

Who is watching 3D movies in theaters? The survey results point to young people, and those without a good education. According to the report, 27% of those between the ages of 18 and 29 (the youngest age group in the survey) have seen a 3D movie within the last year. The rate drops off steeply with age, with 19% of those between 30-49, 12% for 50-64, and only 10% of those 65 and older.

That the ages skew young is hardly surprising. When you consider some of that were released (at least in some theaters) in stereoscopic 3D -- such as Polar Express, Chicken Little, Meet the Robinsons, Journey to the Center of the Earth, Bolt, etc. -- you wonder how the demographics would look if the survey had included the 5-10 age group. Even the allegedly adult 3D movies, such as Beowulf and My Bloody Valentine, don't skew towards the more mature grown-ups.

We not likely to see a 3D Frost/Nixon any time soon. But an action flick with a broader demographic appeal, like The Dark Knight or Casino Royale, could change the demographic.
