Also, here's a 101 Reload from a 2008 Gary Drake post-
I was working in Asheville as a midday DJ in 1972. I got a call from Bob who had come to town to listen to my competition, he liked me instead. I did 9a-noon on 'KGN. Bob was a marketer. We did everything from putting stickers all over the city, bumper stickers, every on air game or contest we could think of, including the LAST CONTEST. We even did WPFC on WKGN. After promoting this for over a week, we found out that WPFC means We Play Fewer Commercials- at least during the promotion.
