It's a demographics issue - all the 20-somethings I know follow shows, almost nobody does the whole "I just want to see what's on" thing anymore. There's a major shift in how people use TVs, and the new user mode supports intentional watching (as opposed to passive surfing).

This is supported by the rise of DVRs, allowing people to choose when they want to view their content without delving into the online realm of Hulu, Netflix, etc.

The problem right now is that none of the major online streamers have really good integration into any TV set. There also does not exist a good discovery system ("you like House? You might also like...") for anyone except Netflix, and they're more of a movie house than a television one.
