Radio ratings

Ever been curious how the radio station you listen to does in the ratings? Radio & Records posts the Arbitron ratings for every market on a continuing basis. The charts include the call letters (but not the frequency), the owner, the format and the rating for the past several quarters. Of course, NPR and other non-commercial stations aren’t included.

The rating shown by Radio & Records is—I believe—the average number of persons over age 12 that listened to a radio station for at least five minutes during one quarter hour at some point during the day. This is expressed as a percentage of the total possible audience for that market.
