Professional media would do well to listen to Doc Searls - he's got his finger on the pulse of where media should be going:
So now comes news from Michael O'Connor Clarke that the CBC is quietly releasing one of their most popular shows on BitTorrent. And that it's DRM free. As it ought to be.
As Doc says, major media here in the US is still mentally bound to the airwave and frequency idea (even as the analog spectrum is about to be reordered). They need to figure out that their current audience, which is bound by time and position is much, much smaller than their potential audience - which would be happy to watch them at times of their own choosing.
