NBC Sports has launched versions of its Live Extra app for [Roku & Apple TV] making sure that you won’t miss out on the Golf Channel, the Olympics, Sunday Night Football and some internet-only events, such as certain Premier League matches. You’ll still need a qualifying TV subscription to watch in the first place, but this beats missing out on some big-screen sports simply because you’re visiting friends. – Jon Fingas, Engadget http://ift.tt/1QBpJJm
