The problem with Pool as a TV sport is that even among the vast majority of players, it is a participation activity not one they want to watch.
Ask around at your next league or tournament. I find that very few players follow the sport. Few even know who the pros are or how they are doing. I hang out with a lot of very active players, there are only a couple that can have a conversation about the pro scene. The rest only know Efren or Earl.
Not sure how you expect to bring in huge numbers of viewers when the people who play the game don't care to watch it. And no, ESPN isn't the answer. Very few people under 40 watch cable tv. Streaming is the future, viewers will have more options to watch what they want exclusively. It would be nice to be able to pay for one stream to watch the pro's but there is not currently a tour. So we are stuck with 100's of different streams to find and pay for. Having one or 2 would be better. The quality would improve. Look at Matchroom or Accu-Stats. To me, these are the gold standard. Camera work and announcers are tv production level. All the other streams with one camera position and announcers reading the chats need to die off or be free streams on facebook live.
