FOR IMMEDIATE RELEASE

Arbitron response to New Jersey Office of the Attorney General subpoena
Company maintains Portable People Meter radio ratings services are valid, fair and representative
of the diversity of the radio markets measured

NEW YORK; September 15, 2008 – Arbitron Inc. (NYSE: ARB) today released the following statement in response to the subpoena of the New Jersey Office of the Attorney General regarding the Portable People Meter^TM radio ratings services.

Arbitron is justly proud of the quality and reliability of its Portable People Meter radio ratings services. Arbitron PPM^TM services are valid, fair and representative of the diversity of the radio markets measured.

Broadcasters have long called for the adoption of a more precise and credible audience measurement tool in order to meet the long-standing demands of advertisers who have called on radio to adopt a more accountable radio ratings system on par with those of other media.

• The difference between PPM ratings and diary ratings is a function of the survey tool, not the sample.

• Broadcasters of all formats, including urban and Hispanic, who have embraced PPM as programming tool, have increased their audiences and their standing in the marketplace since the initial release of electronic ratings;

• Arbitron will continue to adhere to the Media Rating Council Voluntary Code of Conduct and will continuously strive to improve the PPM radio ratings service.

“Once again, the media industry should be concerned about these continued political encroachments on the valuable role that the Media Rating Council fulfills,” said Steve Morris, chairman, president and chief executive officer, Arbitron Inc. “The MRC oversees a well-established, widely-accepted process that has served television, radio, print, Internet and other ad-supported media for more than four decades. The MRC has also been a driving force behind the important and continuing quality improvements in the ratings services that the media industry counts on.”
