There was some interesting news last week about Hulu - they stopped distributing with tv.com and Boxee. Now, they could be trying to build an online version of a TV station - like Facebook, trying to get all the clicks to happen on their site. There's also the possibility that cable networks are getting antsy about the whole streaming video thing:

Could it be that the big cable companies are pressuring TV networks and film studios to scale back the content they provide Web services? Peter Kafka from All Things Digital certainly thinks so. Although it’s purely speculation, it's believable, especially given the financial incentive cable networks and operators have to preserve the current cable TV business model. In fact, Glenn Britt, CEO of Time Warner Cable blamed part of the company's $8.16 billion loss in the fourth quarter on Web video services, which have been luring customers away from cable companies.

I have no idea whether that's true or not, but I do think cable operators are at the starting point of a downhill run to pain. Just as the web has been steadily destroying the newspaper business, I think we're starting to see the business model for TV and radio change over. In an on-demand culture, the whole "must see tv" thing just doesn't fit anymore.
