From our "Think Tank" of 1000 people only 2% of them would watch pool no matter what the prize money or who was playing (Jeanette would be an exception).
On the other hand if they knew the players through stories that are entertaining those numbers shot up to over 70%......'The Game is the Teacher'
Then, when gambling was thrown in {the equation} the numbers shot up to over 80%.....hmmm

Of course there's much more information they gave us that forms the "solution picture"......the good news is pocket billiards is as popular as any other sport or game, it just needs to be introduced properly - in the an order that consummates the general public's appetite.
That doesn't surprise me.
We have talked before about how compelling the players are to watch once their stories are told and the audience becomes emotionally attached. This angle is great and it obviously works. It is a required ingredient to a successful production IMO but it alone is not enough to get the full effect IMO.
While it is important for the players to be compelling it is even more important for the game to be compelling. You said when gambling was introduced the interest went up. I can see that. I asked earlier a question of why people watch sports. The essential factor is clear when we look at what a game is. A game broken down to the core ingredients are defined as 1) anything that involves one or more people 2) a goal to accomplish & 3) an obstacle of obstacles preventing the goal. The obstical could be a direct opponent like a defensive linebacker in football a physical object like a bunker in golf, or a mental obstical like the pressure associated with making a shot when big bucks are on the line.
The more people can recognize the goals and the obsticals in a sport the more compelling the sport is to watch. When someone watches supercross it is easy for them to understand the goal is to perform a certain number of laps before all of the others and the obsticals are easy to identify, it is easy for the viewer to picture how impressive it is for the riders to make the huge triple jumps or travel through the whoops etc and it is therefore somewhat compelling to watch even if you don't ride. When someone watches boxing it is easy to figure out the goals and obsticals and how challenging it is for the athletes and therefor it is somewhat compelling g for people to watch. And so on and so on with other sports.
Lets look at pool though. Even with the brief explanation of how to play rotation games most people (not pool players) can't follow the goals of the players on their own. They can't even tell which ball is next or what ball they need to shoot without the help of the commentator, much less when someone gets too straight in or creates too much angle. And what about the obsticals? I wouldnt be surprised if they wonder if there are any obsticals. The game looks easy and what's compelling about that? Even the mental pressure is unrecognizable in most productions, only the hardcore players can recognize it and are impressed with big packages.
People can say what they want about how hard bonusball was to learn but to the casual fan the concept was easy, purple, orange, and black. The goal was recognizable. The game was clearly more of a struggle too. The players didn't just get up and run racks with no emotion. There was interaction, strategy discussed, shot clocks, obvious pressure situations.
Ok, for those who say no more bonusball talk, let's look at the Mosconi cup. The pressure is brought out and easier to see making the game more compelling. Or what about eightball, isn't that game easier for the casual sports can to recognize the goals. If only the game presented more obsticals, it's too easy, as is nineball, or tenball IMO, but we can find ways to make them compelling if we try. How can we add in more pressure? How can we educate the fans so that they understand the goals and obsticals? A more animated crowd that reacts to certain situations perhaps?
I believe the answers are there we just have to find them. Mosconi cup is a step in the right direction. Bonusball was a step in the right direction IMO. I believe that with guys like you seeking to get there you will succeed. It's just another game,the goal is to put pool on the map & one of the obsticals is generating fans. We will win!
