Hulu+ has most network TV the day after it airs. Netflix has some network TV when the DVD set comes out. The major thing missing from Hulu+ are CBS shows. NBC, ABC, FOX and CW are all there though. Lots of UK shows too. For TV, Hulu+ eats Netflix's lunch.
It might be worth mentioning that Hulu+ has commercials... despite the fact that you pay for it. Honestly, that turns me off. I suppose if my only alternative were cable I might swallow hard and live with it. Thankfully, I get most broadcast networks OTA.
