For Showtime (which I pay for) I usually have to find a stream for their fights because they aren't played live where I live. If a fight is on at 9 pm EDT, it will be on at 9 PM MDT (where I am right now) 2 hours later.

For HBO, I would like to see a weekly show maybe half an hour long that talks about the sport in general who the names are, what's going on etc. It would be an easy way to promote their fights and fighters. I would like to see some kind of system to their fights not just the routine of Upcoming star vs. Guy with a name that used be a contender. I think something that would help boxing would be making a big knockout bracket system top 4 fighters from each division, Showtime has done it and it makes sense. I want to be clear though keep it simple single elimination, semi-finals and final. Make the pay to the fighters contingent on their success in the tournament to give them incentive to push it to the limit.
