As a viewer, I like the concept of On Demand and I do watch TV shows for free on Demand. But how does this work? The channels don't get advertising revenue, and this would screw with the traditional viewership rating system. But is seems like the wave of the future.

And hat about internet viewership?

It seems like the networks are passing up advertising revenue, and I can't help but think that will somehow trickle down to the actors.
