It was only a few days ago we talked about the HBO Go app from Comcast hitting the Xbox 360, and now, it's here. As promised, Comcast flicked the switch on its HBO Go support for Microsoft's entertainment (its no longer just a gaming) console.
Viewers who have a Comcast cable subscription, and the Xbox 360, can now sign-in and watch virtually all of HBO's catalog on-demand. Viewing counts toward the 250GB data transfer cap, unfortunately. Comcast was excluded from the initial access for reasons that even now, haven't been explained.
Most believe that the answer is more of a matter of slightly longer negotiations between the three companies in question: Microsoft, HBO and Comcast. At the moment, Bright House Networks and Time Warner Cable-based customers are excluded, but the reasons above are most likely at play.
