The 2014 Winter Olympics in Sochi, Russia, are well under way and it's clear that this year's Olympics are a multi-device event. One would not be considered too strange to be sitting with a tablet propped atop a desk or coffee table, streaming a curling competition, while simultaneously using a smartphone to stream a speed skating heat. All while the television is replaying footage of a women's ski jump event on NBC Sports Network. Such behavior is not unusual, at least for many U.S. consumers, but it helps explain why NBC Sports is continuing to invest in over-the-top streaming. During the 2012 Summer Olympics in London, the broadcaster made most of the events at the Games available to either view live or download online through its Live Extra app or at its website, nbcolympics.com. For the 2014 Sochi Games, all the events are available online, either live or to download, for authenticated users.
