As much as I would like to see big prize funds I just don't think you will see it happen.
Getting bowlers to pay more, good luck with that. Look at the last outcry over the raise in USBC dues and that was less than $5 a year. Look at how many don't want to sanction anymore.
Unlike golf, you can't get over 100k people in to spectate during a tournament. So virtually all the money has to come from TV and other sponsors.
With maybe 1.5 million sanctioned bowlers left, I doubt it a third of them watch the PBA on TV and they are for the most part not in the 18 to 35 demographic sponsors want. Just not enough eyes.
In the 1980's when top prizes hit $100k there were far fewer cable channels and 8 to 9 million sanctioned bowlers. The viewer demographics were much better. There wasn't 15 hours a day of NCAA Football and basketball. Not to mention the NBA, NFL, NHL, MLB, and now soccer.
Plus the normal joe on the street would say why pay to see something I can see for free every night at some bowling center. The scores maybe better in leagues than what they show the pros bowling. And they don't understand lane conditions, it looks exactly the same to them.
