Arbitron Updates its MRC Accreditation Status

COLUMBIA, Md., Jan. 11 /PRNewswire-FirstCall/ -- Arbitron Inc. (NYSE:ARB) today issued the following statement regarding the status of the Company's application for accreditation by the Media Rating Council (MRC) of the monthly Average Quarter Hour (AQH) radio ratings data produced by the Arbitron Portable People Meter(TM) (PPM(TM)) radio ratings service in 21 local markets.

Arbitron has been informed by the MRC that it has accredited the monthly AQH radio ratings data produced by the PPM service in the Minneapolis-St. Paul market - which joins Houston-Galveston and Riverside-San Bernardino as accredited markets for Arbitron's PPM ratings service.

Additionally, Arbitron has been notified that the MRC will deny accreditation to PPM services in the following local markets: Atlanta, Baltimore, Boston, Chicago, Dallas, Denver, Detroit, Los Angeles, New York, Miami, Philadelphia, Phoenix, Pittsburgh, St. Louis, San Diego, Seattle, Tampa-St. Petersburg, and Washington, D.C. Further, the MRC closed without action audits for two California markets (San Francisco and San Jose) and these two markets remain unaccredited. Arbitron will collaborate with the MRC to re-audit each of these markets in 2010.

The Company is encouraged by the accreditation of Minneapolis-St. Paul, which further validates our Radio First methodology. The Company understands the MRC's need to close out old audits. Arbitron believes that across all of its PPM markets it has demonstrated significant progress and ongoing commitment to improvement requested by the MRC.

The Company continues to adhere to the MRC accreditation process, and looks forward to working together with the MRC on that process.
