CBS, NBC to Offer TV Shows for 99 Cents
According to an AP report. "CBS and NBC have announced deals to offer replays of prime-time programs for 99 cents per episode, shifting television toward a sales model that gained popularity with downloaded music." But the shows will only be available over Comcast on Demand, not for download.
NBC's offering will be through DirecTV. CBS will be through Comcast.
I misread your question. The cost difference is $1.00. Comcast is offering their product (with commercials) for $0.99 while Apple is offering their product (without commercials) for $1.99. Again, the Apple download can be viewed multiple times, whereas Comcast is essentially rebroadcasting for your viewing pleasure at a time more convenient for you. You are paying for the service of the rebroadcasting, not a downloadable product.
With the Comcast deal, you buy an episode for $0.99 and you can watch it as much as you want until the next episode airs, at which point it becomes inaccessible. This is the same VOD model they use for most of their programs: build in an expiration date, much like a video rental.
