The only thing I know about the show is that the
one time my HS team "tried out" to be on the show we
lost by five points. IIRC, you had to win three
"non-TV" games to get on TV.
It's been on for *at
least* 20 years because I remember it from my childhood
and it was well-established when I was in high
school. I have a feeling it's probably been on much, much
longer.
