Cable: Verizon FIOS, Cox and of course Comcast's owned Xfinity with G4TV being a in-house network. no word yet on whether or not NBC Universal is negotiations with Dish, DirecTV, Charter Spectrum and other providers on if they will air it on a channel on those lineup, even if they try to see if they can use the spot that will be surrendered by NBCSN once it folds next month.
streaming: Youtube and Twitch.
