The new-TV folks think it applies to all television. Here again is an ideal that's evolved without a single shred of evidence that anyone wants it. It reminds me of the customized newspaper or magazine idea that was promoted on the Internet. Some users liked the idea, but it was ultimately a disappointment because editing and designing a customized product for yourself or anyone else is probably not your job. Professional editors can do a much better job of organizing news than you can, just as TV professionals should be able to do a better job of programming.
Incompetent programmers do come along, but they're quickly replaced.
It's all part of the competitive environment. Although the Internet has sucked up some viewing time, it's not a threat to television with or without streaming media. Much of the problem with television is the executives who feel more comfortable within a siege-mentality framework. These are the sorts of companies that enjoy the siege mentality. They see threats all around and feel they must change to stay alive.
