American pool lacks a centralized lobby to fight for it.
Case in point:
(1) We've just had a 4 month break in live sports, and the major sports networks flailing to show whatever new content they could - down to broadcasting video games and Korean baseball.
(2) Every pool hall in the country was a big empty building, and pool is among the easiest sports to socially distance (lag on 2 different tables and measure if you want to take that step, otherwise neither player really needs to be within 15 ft. of each other). Next to no staff is required, and you can pull off a well produced event without anyone close to each other. This should be 100x easier (and faster) to pull off than any other sport that has worked to come back.
(3) Alternatively, there's a ton of commented pool content already out there …. and NOBODY thought to start pitching it to networks when there was a gigantic entertainment window in the US to step through. Seriously, there was no live (or previously unseen) competition out there - during the one time in our lives all 300 million+ Americans were simultaneously bored.
(4) The last time pool was widely shown (I remember it from the 90's - ESPN2 era I believe), it suffered from the belief that common among all broadcasters at the time that they need to pander to the least knowledgeable viewer, this lead to a lot of "that's a great shot (with no explanation given)" type comments. . From other sports, (whether Tony Romo in football, the various metric-derived analysis from the other sports, etc...) it is now clear that if you go into proper level of details, the less knowledgeable viewers appreciate it more than they appreciate being pandered to - and this ends up creating its own subculture centered around the details. Getting into more details on the announcing side may help close the perception that run-out pool is "boring" to watch.
