I agree a bit as it was neglected by most pro events in the USA.
But for instance in Europe, it's one of the discipline played at the European championship so it is played and practiced, it also became a game that is played in Eurotour stops.
As Europe represent one of the strongest continent in pool, I would not say that 8ball is not so meaningless...
Since the PBS run 8balls events, pro events with good money, many players has started to put more effort and practice into it, especially in Asia were the game was hardly played.
Chinese Hey Ball is also bringing a lot of focus into the game.
Most amateurs play or start playing 8ball, it is the most known pool game in the world with all it's variations. I think that if the governing bodies of pool want to make pool bigger, they should put more focus on 8Ball as it's a game that the average people know and can relate to and it can grow bigger audience, the Ultimate Pool franchise proves it to be right.
