The vast majority of the potential fight-viewing 30 million American HBO-subscribing customers wouldn't know what an internet stream was if it injected them in the arse with PEDs. And if they do want to watch the fight they want to watch the fight on their great big telly, not on some shitty blurry choppy two inch by four inch screen that could get shut down at any minute. Sixty dollars may seem a lot to somebody from a country where that's the average monthly wage but it's fuck all to an American who wants to see something.
