A lot of hype has been made around the $1.99 offering of a limited set of TV programs via iTunes 6.
This isn't a new or original idea. SciFi channel offered a few episodes of Battlestar Galactica online, and now CBS if offering weekly streams of it's fledgling show, "Threshold". The show is good (ok, it's manageable) but it's got Brent Spiner so how bad can it really be?

It's an interesting marketing ploy- would be even more interesting if they Podcasted it and offered as a WMV download for Smartphone, Media Center, Pocket PC, and er... other devices :)
