PPM (Portable People Meters)
Thursday, June 24, 2010…..Arbitron activated more than 700 Portable People Meters around the Triangle. This day officially launched the era of electronic radio measurement in North Carolina. It is a day that will live forever in the minds of media buyers throughout the area. Really?
PPM is a system developed by Arbitron to measure how many people are listening (or at least being exposed) to individual radio and television stations as well as cable TV. The PPM is worn like a pager and picks up on hidden audio tones within a station or networks audio stream, logging each time it finds a signal. The system was designed to replace those antiquated written diaries that many in the industry had issues with. Issues such as sample size and response fluctuations that led to ratings wobble, certain demo and ethnic groups were over- and under-represented, reported listening was exaggerated in certain dayparts, and a good deal of cumulative listening was not reported at all. Still, this was what we, as media buyers, had to “trust” when putting radio buys together.
I for one am excited about this way of measurement. I hope that it truly makes a difference in how radio is bought in this market. While I believe that a lot of buying is based on gut instinct and knowing the market, numbers have to play a part in it. I have always marveled at how every radio station can position themselves as #1….we are #1 in reaching boys 12+ after midnight….we are #1 in reaching adults 65+ on the weekends. I want to know who is #1 in reaching my demo, whatever it happens to be, during the dayparts when they are listening. I hope that this new PPM will help me decipher that a little better.
I wonder what will be next? Perhaps we will all wear some type of tracking device that will pick up on every message that is sent to us. I have read that the average American is exposed to between 850-5,000 messages on any given day. There doesn’t seem to be an exact number that I can quote. Either way, there are a lot of messages being drilled into our brains constantly. How many do we actually remember? Well, at least with the PPM not only will Big Brother be watching us he will be listening to us as well.
