Despite the TV industry’s efforts to push 3-D televisions, the technology may be best suited to cinemas where people can devote their full attention to the screen, writes the Economist. “Three-dimensional television is coming whether you want it or not. But after the novelty has worn off, it is likely to have only limited appeal — serving mainly viewers interested in sports, movies and video games. The problem is that couch potatoes watching television at home, rather than a film in the cinema, rarely devote themselves entirely to the visual experience.”
