Is it time to cut the cord on cable TV?

If you gave or got a TV set, game console, Blu-ray player or DVR for the holidays, you might become the kind of person who scares executives who run movie and television production studios, broadcast and cable channels, and cable and satellite systems. Many of these devices now make it easy for people with home broadband networks to feed content from the Internet, including Hollywood movies and TV shows, onto their TVs.

What media moguls fear: 2011 could become the year when increasing numbers of people watch Web TV content from sources including Netflix, iTunes, YouTube, Amazon, Vudu, Hulu Plus and Crackle — and trim or even cancel their monthly subscriptions for cable, satellite or phone company TV service. "You can't have a discussion in the media business today without this becoming the sole topic of conversation," says Craig Moffett, a media analyst at financial services firm Bernstein Research. "This is the whole shooting match." It's sure to be a big topic this week at the International Consumer Electronics Show convention in Las Vegas, where companies will unveil the new Web-enabled TV devices they'll sell this year.
