Buying NBC isn't the only big news from Comcast happening at the end of the 2009. Today they're launching a new online on-demand service. It's only for Comcast customers, but I'm a Comcast customer, so I'll be able to watch it!

It's called XFinity, which sounds like that name for the next Stargate spinoff but is actually a new part of the Fancast site where you can watch TV shows from channels like HBO, AMC, A&E, STARZ, The History Channel, and Cinemax. That means you can watch shows like True Blood, Entourage, Mad Men, The Colbert Report, Big Love, and many other shows. (By the way, right now Fancast is running a marathon of Friends Christmas episodes.)

Now that Comcast owns a big chunk of NBC, I wonder how this service could someday be combined with Hulu in some way, or if launching this service will affect Hulu in other ways.
