Comcast to announce Fancast video portal: watch out, TiVo and Blockbuster stores

Here at the Consumer Electronics Show in Las Vegas, the most overarchingly important innovation I've seen so far just has to be Comcast's new Fancast service.

Fancast.com will let subscribers search for and manage their TV shows as well as movie viewing. You will be able to access personalized listings, and eventually, program your DVRs with Fancast.

Not only that, but Fancast will be a portal of sorts, allowing subscribers to search for available movies on the websites of Netflix, Blockbuster, Amazon and iTunes.

That, and an increasing number of high-def video on demand movies and tv shows available via Comcast video on demand by the end of this year, encourages me to ask two questions?

Is Fancast.com a TiVo killer?

While Fancast will have Blockbuster.com as a content partner, will Fancast pair with Comcast's expanded Video on Demand offerings to become a Blockbuster brick-and-mortar killer?
