Bbbing only channel never happen. Unless someone pumps their own money into it, and at best breaks even with sponsorship money should the channel be on air that long.
Better idea, would be to create a "strength" channel with powerlifting, strongman, bodybuilding, maybe fitness, etc, ut even that probably wouldnt take off.
Another option is to put a 1-2hr segment on a sports dedicated channel every week or bi-weekly.
Unlikely, but would be good for the fans. And pervs.
