I've commented before that I don't watch much TV. However, if this concept works out for CBS and NBC, I think other networks will be quick to adopt it--and you might see me watching more TV (making the assumption that there is something on I deem worth the effort).
Of course, they want to do this by pushing it to a DVR that you're paying a subscription to use, and I'll bet that you won't be able to burn a copy of the show, but at least they're starting to get the idea. Now when they make them available as $0.99 video downloads via the Internet, they'll really be onto something.
But I won't be holding my breath. Old media isn't enthusiastic about changing, and they're only going to do so kicking and screaming. But it is fun to watch. Anyone got earplugs?
