What do you use as a reference to the state of pool? Pros not being on tv. Pool halls closing. They are completely different entities of the state of pool as a whole. I don't have number but it's seems leagues get larger every year. Seem more products are being created and sold. More companies which means more people being emplyed. Pool is growing every year. Pros have their own issues. Taxes and regulations may be why pool halls close. Or it can be competition of entertainment. Or it can be management. So many reasons why a lot of small businesses go under. Maybe I am wrong but every time I see a new production cue company start up. Make me think pool is doing well.
The evidence is mostly empirical, I admit.
The proof I use is interviews with pro players about tournaments now as opposed to the past. I also keep reading about pool halls closing and plenty of league directors on this very forum trying to change the rules, handicaps, etc. to encourage new players.
The numbers I found online made it sound like Pool brings in about $750 mil. a year. That's for products, pool halls, etc. I'm not sure how accurately those numbers are gathered or reported but if it's even remotely accurate then pool is leaving a lot of money on the table. As I state in the full version of the article, some aspects of pool are actually well position to increase profits. However, what is missing is a smooth road from first-timer to beginner and then to regular player.
I also base my opinion that pool is dying from the messages on this very forum. You might think pool is doing well but from what I've seen it's struggling and there's no good reason for it other than a failure to capitalize on the strengths of this sport.
