Long article on the beginning of television and college basketball. The shining moment of College Basketball may have come in the late 1980's when something like 6.5% of sports fans considered it their favorite sport. Since then, that number has dwindled to about half. And yes, there is some source for that but I'm not looking it up.
As to what this board would have been like, there would have been plenty of Hawkeye fans here. Maybe even more than we have today. You see, Iowa didn't have a pro-team. And Televisions only had three channels. Hawkeye sports were accessible by radio and many a fan spent winter nights listening to Jim Zabel.
As a kid, I did. And I watched my Dad scold Lute Olson for every missed free throw or scoring drought as if he could see the game. Clearly, he was an idiot.
Had this board been around then, I'm sure I'd be on it scolding idiot fans and rooting for coaches and players that I saw live from Miller, and on.
