Last June I talked about Arbitron's Portable People Meter (PPM). That's a new way to measure radio listening habits with a small, pager-like device. When that person is near a radio, the device will pick up a specially encoded signal from the broadcast to register this person is listening to station X.
This method of ratings determination replaces listeners having to fill out paper diaries of their listening habits.
The theory is the people meters will be a better measure of what people listen to since the audience isn't consuming media just at home. So if I was at work listening, it counts. If I was at a restaurant it counts as long as my pager can pick up that encoded signal.
The first ratings just came out for this new measurement system.
Take a look at how the ratings altered between the Portable People Meter (PPM) and the traditional diaries.
Looks like the radio pot is getting a good stirring!
