Comcast has multiple competitors already out in the wild. First they have XFinity Flex. Their competitor to Roku. Then they have Peacock, which at the moment looks like a competitor to CBS All Access. Coming soon. Somewhere in between a channel and a platform you have Live TV broadcast. Who knows how they will brand it in the long run (they will want you to pay for their variant of "cable service / satellite".) ATM they have the Xfinity Stream Beta App on Roku. They also have the NBC Family of streaming apps: bravo, e!, nbc, oxygen, syfy, telemundo, universo, usa. They would absolutely benefit from a single "guide" interface like ATT TV Now/ / PlutoTV.
