Being a young bowler(44 years old) I consider the glory days to be the 60's and 70's, before all of this new equipment. The ABC telecasts were immensly popular, owing to the lack of live sports telecasts on TV
and the number of people who bowled in leagues. I used to love listening to Billy Welu and Chris Schenkel every Saturday for those months between January and April. The PBA didn't dilute itself till much later by adding the extra telecasts. It was fun watching [censored] Weber
, Johnny Petraglia, and all of the older bowlers who really invented the PBA tour. I wish I could have been around earlier than that to see the heyday of five-man teams and the big tournament that was held in Chicago each year. Those tournaments had more prestige than the current tournaments do, with perhaps an exception being the ABC Masters. Even that tournament cheapened itself by going to a PBA finals format instead of staying with the my series can beat your series matchplay. Oh well, TV
corrupts some and assists some events in getting better. I'm sure others have opinions as to the Glory Days. I'll check back to see how much I didn't mention.
