Comcast has launched its long-awaited (by some) 24-hour 3D channel, Xfinity 3D. This adds to Comcast's other 3D offerings like ESPN 3D, the 3D events channel, and the 3D on demand movies. The channel launched with broadcasts of a Kings of Leon concert and the NHL Heritage Classic 2011 hockey game.

You can expect 3D nature documentaries, animated features, concerts, sporting events, and performances, although the schedule doesn't look to include too many hit movies or concerts at the moment. That said, this could be similar to years ago when a few HD channels were first lit up with nature shows and soccer games, giving HDTV owners something to watch. What do you think? Will dedicated 3D channels spur sales of 3D television sets?
