Some time ago I received a survey in the mail that asked me if I would be willing to log my radio listening habits for two weeks and report the results. Everything was written down on a card, day by day, what I listened to, what station and when. They gave me a few bucks to participate.
The next thing I knew the big A.M. station in our area carried ads that said it was “Number 1” in our city. I’m glad to have been a part.
