New York - Dec 31, 2008 - Arbitron has commercialized its Portable People Meter (PPM) radio ratings service in four new local markets. The radio audience estimates for the December 2008 PPM survey month (Nov. 21-Dec. 17) have been delivered to subscribers in Dallas-Ft. Worth; Atlanta; Washington, DC; and Detroit.
PPM audience estimates are now considered buy/sell currency in 14 local markets. The latest four join New York, Los Angeles, Chicago, San Francisco, Houston, Philadelphia, Nassau-Suffolk, Middlesex-Somerset-Union, Riverside-San Bernardino and San Jose. According to Arbitron, these markets account for 51.7 percent of the estimated radio station revenue in the top 50 radio markets.
