Radio markets by the stations and numbers: PPM Portable People Meter
What the heck is the Portable People Meter?
The PPM is a passive, electronic measurement system that is replacing Arbitron’s diary-based ratings in the top 50 radio markets. Designed to automatically detect radio signals wherever a listener may be – in the car, at home, or at work – PPM offers you a wider range and better quality of information about how and when consumers listen to the radio.
This is severely off topic, again, but interesting to some (me 🙂 . Feel free to yonder off into this here chart graph thing, and you may be surprised about demographics, and more specific radio station cumulative audiences in your city. A la Carte’
