I've noticed several others asking similar questions about activating the History Channel App on either Xbox, Roku, or Apple TV. While I understand there may be a cost to Cox for providing this service, I find it hard to believe a major cable/internet/phone company would not participate. Even if the individuals wishing to subscribe were charged a small fee to do so, it would be better to offer this service rather than blocking it to all.
Obviously, it can happen. Please allow those of us who wish to watch this channel do so.
Thank you.
