Threads like this take away the focus from the real issues that plague this sport, the game played and how freaking boring it is for the spectators currently. THAT is the problem with pool and it has been for decades.
It isn't a problem in the Asia or it isn't a problem with snooker in England. Pool actually has decent television numbers. Enough that ESPN uses as filler programming. Will pool ever be the NFL? Nope. But, it can carve out it's own little niche.
The problem that I see it is the lack of organization within the sport itself. The industry doesn't/can't/won't help support a viable tour. The players are short sighted but I can understand this because they are just trying to survive. Promoters can't make any money running tournaments, etc, etc, etc.
Yes pool can be boring to watch but so is golf, baseball, chess, poker, to name a few. Here is my unprofessional opinion on how to make the game grow:
1. Have some semblance of an actual professional pool tour. Take the existing large scale tournaments such as the DCC, SBE, BCAPL Championships, US Open, Joss Tour finale, etc. as the basis of the tour.
This pro tour will be bare bones. Create a points structure that can determine player of the year, Mosconi cup invitations, etc. There will need to be some minimum requirements for a tournament to be "sanctioned" a tour event. Say minimum $10,000.00 added, certain rules, etc. But beggars can't be choosey at this stage of the game. Just compromise so that it can work.
2. Get at least the finals on TV. Streaming is an interesting avenue but the most people that I have ever seen watching a stream is about 2000. That number is world wide. For the sport to grow, it has to get on television. There are a bazillion channels on cable (ok not that many). I watch local sports such as high school football on television so getting billiards on a channel say Versus, etc. should be possible. Again, there has to be some sort of organization of the sport for this to happen. The WPBA had the right idea with their affiliation with ESPN. But, their business model needs to change with the current economic conditions.
3. Market,market, market the tour stops. Did I say market? Use Guerrilla marketing techniques, create an official program with player bios, create a media package (include free press passes, program, etc.), pro am event for charity, use grass roots marketing (word of mouth), etc.
Hopefully, the tour catches some momentum and gets picked up by a network or corporate sponsor. If not, then it can at least still be viable. The problem is that it takes an organized effort between the promoters, players, etc. Good Luck with that.
