Remember that internet plus HBO deal that Comcast introduced late last year, presumably to give online-savvy folks an incentive to subscribe to cable again? Turns out it doesn’t come with the ability to watch any live streams from Sochi, which is starting to get people in Comcast’s web forums very upset. For the second time, NBC has been restricting its live online Olympic coverage to viewers that have a pay TV subscription. Viewers who want to tune into the network’s 1,000 hours of live streams need to authenticate themselves, as it’s being called in industry-speak, which means they need to log in with the username and password they use on their TV provider’s website. But a number of Comcast customers now notice that despite paying for cable, they still can’t get access to those Winter Olympics live streams.
