You probably don't think of your cable box as a place to watch online video, but Comcast is determined to provide more reasons to stream from your set-top: it just brought over 30 new internet video sources to the X1. Virtually all of the content comes from big-name TV networks like ABC, BBC America, Discovery and (of course) NBC. Their offerings initially focus on news and sports, but they'll eventually include more extras and "complimentary" productions. This shouldn't be a mere rehash of what's already on your DVR, in other words. No, this won't persuade you to keep cable if you were already thinking of cutting the cord. However, it might serve as a nice complement to the TV you're already watching -- you can stream that behind-the-scenes bonus clip while remaining planted on the couch.
