How cool would it be if Apple/ABC/other sources collaborated on a permanent subscription model for network TV content? A consumer would pay a set fee for a certain number of episodes, which would be a certain percentage cheaper than if you bought an entire season's shows individually and got automatic delivery of the content. It's retooling information by applying new media applications to proven concepts, taking a page right out of Sports Illustrated (pun intended), and from blogging/podcasting.
Think about it: assign users a secure account in the iTunes Music Store. They agree to pay $25.37 for a 15-episode season of "Grey's Anatomy" (15% off the cover price of $1.99 per episode). Add an incentive - subscribers exclusively get an extra bonus video of cast interviews, outtakes, etc. - and programmatically subscribe the user's local version of iTunes 6 to an authenticated RSaS feed that delivers their shows according to a set schedule (an additional subscriber-only incentive might be they get the video a few hours earlier than its released in the ITMS).
For the consumer this would mean cost-effectiveness, guaranteed delivery, convenience and reliable viewership. And the networks get more money up front, regardless of the quality of their programming, the ratings of their stuff, or whether the end-user actually watches their stuff, or not. It's the perfect application of RSS to paid content.
