You enjoy watching pool. I enjoy watching pool too. Most AZers probably enjoy watching pool...because we're addicted to pool.
But 99.9% of the rest of the U.S. audience would rather watch skateboarding, beach volleyball or any of dozens of sports on cable TV. Those sports are easy to understand and appreciate in the first two minutes. There's an excitement to seeing a kid twist and turn in midair and land on the skateboard without missing beat. It looks hard so we appreciate the skill.
But even we get bored when a pool player taps in ball after ball (or, God forbid a one-pocket match goes uptable

)
The snooker comparison is very weak because snooker has a long tradition in the UK that pool has never had in the U.S. Also, snooker's viewership numbers are dropping every year (despite having some of the most exciting players in its history) while other sports viewership in the UK are increasing. It appears that UK snooker and US pool are on the same trajectory (down); only difference is that snooker is starting its fall from a higher level.
I have nothing against changing/refining the rules and equipment of pool to make the game more enjoyable to play or watch. But make those changes to please the current players and fans...because it isn't going to attract new viewers.
