Everything you need to know about NBC's Winter Olympics coverage but were too bored to ask

The net spelled it all out in a press release this morning, touting how NBC will combine with USA, MSNBC, CNBC, Universal HD and NBCOlympics.com to carry the first all-high-def Winter Olympics with more than 835 hours of all 15 sports from Vancouver.

Get some sleep now. Or wait until the Games begin.

The 17 days in Vancouver, starting Feb. 12, average about 50 hours a day of coverage. The 1976 Innsbruck Winter Games that ABC did had a total of 43 1/2 hours. We find that to be remarkable, since most Americans even then thought that was pretty much overkill.

NBC will have an afternoon, prime time and late night segment that take up about 193 hours. Even though Vancouver is in the Pacific Time Zone -- hey, so is L.A. -- the men's and women's figure skating, alpine skiing, speed skating and snowboarding will be delayed in prime time.

USA Network has 41 hours of all the curling, as usual, plus U.S. men's and women's ice hockey. MSNBC takes 100 hours of al the other hockey, plus speed skating and some figure skating. CNBC has 100 hours of what's called "long-form" sports, including curling, hockey and biathlon.

NBCOlympics.com has 400 hours of live stuff, with 1,000 more hours on demand to replays.

And after it's all over in late February, Jay Leno will return to his usual 11:35 p.m. spot. On NBC. That's what they're saying.
