Case Study

RADIO'S PEOPLE METER RATINGS

The idea When Arbitron instituted portable people meter (PPM) ratings in Philadelphia and Houston in 2007, it changed the way advertisers and radio station owners thought of their audience. In Philadelphia, the first sets of ratings showed dramatic differences from the old diary method of keeping track of people's listening habits. Some stations even changed their formats because of the findings. The PPM is an example of how an audience measurement technology can change the nature of reality for a media industry about its audience. It caused a lot of controversy and deserves to be examined in more detail.

The method Using a periodical database, follow the discussions that radio and advertising executives have had over the past several years about problems with Arbitron’s diary method and with the benefits and problems that the PPM technology would bring. If everyone understood the problems with the diary method, why were station owners loath to move over to the portable people meter? What were problems that Arbitron found when it tried to implement the new technology? How hard was it to roll out the technology in Philadelphia, in Houston, and beyond? Is it right to assume that the PPM gives the radio stations and their advertisers the correct read on what stations are most popular and when? Do you think it represents the last word on radio ratings?

Write a report of your findings that addresses these questions and this more sociological one: In what ways does the PPM experience show how an audience measurement technology can change the nature of reality for a media industry about its audience?

How important do you think “localism" should be in radio? How would you describe what it should mean?
