When television made its debut, 14.1 was obviously the primary game being played for titles. Read: [sponsored titles]
However, there was still, as always, a STRONG undercurrent of gambling in the pool world, that already included games like 9ball, kelly, cutthroat etc.
The TV producers realized real quick that 14.1 is not made for television, and the broadcast/editing technology had not developed to the point of being able to utilize instant replays and multiple camera angles with instant statistics in front of you. It was boring.
Brunswick, about the same time, was fighting a monumentally expensive pinsetter battle with AMF, was going thru a management change, and was STILL fighting regularly with the pro players they had under contract. ( had been going on since the 1880s)
They finally had enough, and bailed out on their " full time support and promotion" of pro pool in the u.s. and haven't looked back since.
So, when the big sponsor and their event is gone, and nobody wants to show it on tv anyway, the hottest pool action in the country goes back underground and the gambling games return to popularity.
Rinse and repeat.
