Arbitron commercializes PPM in four new markets


On 12/31/08, Arbitron commercialized its Portable People Meter radio ratings service in four new local markets, releasing radio audience estimates for the December 2008 PPM survey month (November 21-December 17) to its subscribers in Dallas-Ft. Worth, Atlanta, Washington DC and Detroit.

Effective 12/28, the PPM radio audience estimates for these markets should be used as the basis for buy/sell transactions of radio commercial time among subscribing stations, agencies and advertisers. In addition, audience estimates from the October and November PPM survey months, which Arbitron had previously released as pre-currency information, are now designated as currency data. The Summer 2008 diary-based radio audience report (June 26-September 17) is no longer deemed “currency” for buy/sell transactions.

PPM audience estimates are now currency in 14 markets: New York, Los Angeles, Chicago, San Francisco, Dallas-Ft. Worth, Houston, Atlanta, Philadelphia, Washington DC, Detroit, Nassau-Suffolk, Middlesex-Somerset-Union, Riverside-San Bernardino and San Jose. These markets account for 51.7% of the estimated radio station revenue in the top 50 radio markets.

In April 2009, Arbitron plans to commercialize PPM in Boston with the release of the March PPM survey report (March 5-April 1.)
