Please explain to us non-radio people what PPM ratings are, and how they are done.
It's a pager like device that detects all exposure to radio. It replaces the diary system which was based on written recall.
Exactly! There's an inaudible signal in each station's audio chain which can be detected by the PPM and which tells it what station you're hearing and for how long.
The net effect of the new technology is that the stations people are hearing are recorded rather than requiring them to write all listening in a diary. The diary method is not without error and people often overstated their listening time to a certain station to which they may have felt some loyalty - and understated listening to radio stations that they hear in an office, restaurant or store.
This has been excellent news for oldies, rock and (to a lesser extent) pop stations. And bad news for many urban and Spanish language stations.
O.K. But how does this device determine that the listener likes the Beatles, Beach Boys and Temptations, but not Buddy Holly, Jerry Lee Lewis, or the Coasters?
