Formats in Flux (Part 1 of 2)
Arbitron’s portable people meter radio ratings service (PPM), stations with a broad appeal and majority male listening audience perform better in the transition from diary to electronic audience measurement.
Stations that rely on a small core audience of listeners for long periods of time get lower ratings for the PPM service compared to the diary.
A radio research study
These findings are highlights of a new format-share study by Research Director, Inc. for Radio and Records which is part of The Nielsen Company. This study focuses on comparing diary and PPM ratings across principle formats in eight major PPM markets. Cities included New York, Los Angeles, Chicago, San Francisco, Washington, Dallas, Atlanta and Detroit.
The future of measuring radio audiences
By the end of 2008, Arbitron will be measuring radio audiences using the portable people meter in 14 markets. In 2009, 19 additional markets are planning to make the switch, and the change will continue rolling out to the top 50 major markets by the end of 2010.
