The Olympic Winter Games are in full swing in Sochi, Russia, and once again, the internet is the place to turn to if you want to watch the competition unfold in real-time, as opposed to the hour-long tape-delay in place on broadcast and cable TV. And this time, NBC is promising to stream everything: All competitions across all 15 sports, totaling more than 1,000 hours of live coverage. There’s only one catch: Just like two years ago for the London Summer Olympics, NBC is once again requiring users to authenticate, meaning that live streams will only be available to viewers who subscribe to cable or satellite TV. This year, NBC is offering multiple ways to authenticate yourself and get access to all the live streaming goodness. The most reliable way to get going is to sign in with the username and password you use to log into your TV provider’s account at NBCOlympics.com/liveextra or within NBC’s mobile app. Read the full story at Giga OM.
