Matthysse-Provodnikov peaked on HBO at 1.38 million viewers and averaged 1.24 million. Chavez-Fonfara peaked on Showtime at 836k and averaged 618k.
Indeed, I expect this to continue though regardless of the matchups simply because HBO has more subscribers.
HBO could have put a replay of a boxing after dark event from 5 years past and it would have drawn more viewers than Showtimes live boxing broadcast. HBO simply has more subscribers. Alot more, and it does'nt mean that their viewership is because they're putting up better fights.
