I've written about how wonderful it is to watch free TV and movies on Hulu in a previous post, but there are some shows that are not available on that site; Fancast fills in many of the gaps with programs like Burn Notice, Lipstick Jungle, Mad Men, and Everyday Italian, all available for free after you sign up (all they want is your email address).
Every episode is free with limited commercials, so it's better than watching on commercial television. Without the need for a subscription service like TiVo or your local cable company, this is a great way to either catch up on a missed episode, or to watch an old favorite. I found Fancast as I was looking for my favorite (now canceled) show, The Gilmore Girls; the offering here is more complete and has less commercial interruptions than the "official" version on the show's website. Fancast allows you to customize your selection by filling out a short preference list and you can actually subscribe to your favorite shows so that you know when a new episode airs.
I love it when I find better choices and quality than at the name brand "retail" location!
