USA Today has an article by Kevin Maney:
Here’s a deeper trend at work, driving decisions and investments throughout the media industry. It suggests that high-definition DVDs such as Blu-ray and HD DVD will not catch fire with consumers soon; that theatrical live concerts by bands such as U2 will only get more popular; and that live sports on cellphones could be a huge hit.
The trend is all about fidelity….Techies describe fidelity as the total experience of something. Seeing a movie in a packed theater, with its wide screen and the social aspect of a crowd, is a higher-fidelity experience than watching a movie on a home system. Seeing a movie at home is, in turn, a greater-fidelity experience than viewing a movie on a cellphone.
