Don’t pay for cable. Don’t pay for iTunes. Watch your favorite shows for free on the Internet. I found all had fewer commercials then regular TV, and you have control over when you’d like to watch, pausing, or rewinding a part you missed.
ABC – Full episodes online, free, minimal commercials. The viewable sizes are a bit smallish for my tastes, but it looks very good. You can catch some previous episodes, too, depending on the show. Note: I had trouble using Firefox on this site.
NBC – You can watch with commentary before, or go straight to the show. Full screen mode is fantastic!! Interface is not the greatest. But they have Heros, what more can you want?
CBS – Full screen on this is great, too, but I find getting to the shows and watching them to be easier than on NBC.
