Philadelphia - Mar 5, 2007 - Clear Channel has agreed to join the Arbitron Portable People Meter (PPM) rating service in Philadelphia. Clear Channel has been investigating several electronics listener ratings systems, and had resisted using the Arbitron service. An Associated Press (AP) article quotes an e-mail from John Hogan, president of the Clear Channel Radio division, that tells advertisers that the company had reached a three-year deal with Arbitron to use the PPM system in Philadelphia, where the broadcaster owns six stations.

In addition, the AP article notes that in its interview with Hogan, Hogan said that Clear Channel is still skeptical about the results of the PPM service and the higher cost, but that Clear Channel was moving ahead in Philadelphia because many other stations had already signed on.
