The opening ceremony for the 2014 Winter Olympics in Sochi officially gets things going Friday night at 7:30 on NBC. The Parade of Nations is always a highlight. Matt Lauer, Meredith Vieira and Bob Costas are scheduled to host. NBC will continue its winter sport coverage through Feb. 23 on NBC, NBC-Sports, USA, MSNBC and CNBC. What you see in prime time will have been taped earlier, but all of the competitions will also be live-streamed on nbcolympics.com (not the opening ceremony, though).
