Two Channels Go All 3D, All the Time 3D broadcasts will be 24/7 starting within a week By Evann Gastaldo, Newser Staff Posted Feb 11, 2011 10:43 AM CST 3 comments Comments Ryan Wiehe, 8, right, and his father Jason wear 3D glasses to watch Time Warner Cable's 3D television at Time Warner Cable NHL Fan Fair booth in Raleigh, NC, Friday, Jan. 28, 2011. (Jim R. Bounds/AP Images for Time Warner Cable) (Newser) – The future has arrived: Within the next week, two 3D television channels will begin broadcasting full-time. 3net, a joint venture from Discovery, Sony, and IMAX, will begin televising Sunday night. The other, ESPN 3D, will become a 24-hour channel the next day, the New York Times reports. Of course, with so little 3D programming available, expect lots of re-runs; 3net will only have around 20 hours of original programming this month. It will only be available to DirecTV subscribers at first … DirecTV subscribers with, obviously, a 3D television set and 3D glasses.
