Arbitron and Clear Channel Sign Multi-Year Agreement
for Portable People Meter Radio Ratings Services in 46 Markets.

NEW YORK, June 27, 2007 – Arbitron Inc. (NYSE: ARB) today announced that Clear Channel Radio (“Clear Channel”), a division of Clear Channel Communications, Inc., has signed a multi-year agreement for Portable People Meter^TM radio ratings services in 46 markets, as and when those services are rolled out by Arbitron. The agreement encompasses all Clear Channel radio stations in those markets that Arbitron has converted or is planning to convert to the Portable People Meter ratings methodology by the end of 2010.

The agreement expires December 31, 2011, and also extends until that date the current contract for diary-based radio ratings in each of the markets covered by the agreement that have not been converted to Portable People Meter radio ratings before the end of 2008, the expiration date of the current diary agreement with Clear Channel.

Clear Channel is Arbitron’s largest radio ratings subscriber and represented approximately 19 percent of Arbitron’s revenue in 2006.

By the end of 2010, Arbitron is scheduled to deploy the Portable People Meter in the top 50 markets in place of the paper and pencil diary method that the company has employed to collect radio audience estimates since 1965.

Editor’s Note: This press release was updated from Arbitron’s June 26, 2007 announcement to remove Clear Channel’s company description. All contractual information remains the same.

About the Portable People Meter

The Arbitron Portable People Meter system uses a passive audience measurement device – about the size of a small cell phone – to track consumer exposure to media and entertainment, including broadcast, cable and satellite television; terrestrial, satellite and online radio as well as cinema advertising and many types of place-based electronic media. Carried throughout the day by randomly selected survey participants, the PPM^TM device can track when and where they watch television, listen to radio as well as how they interact with other forms of media and entertainment.

The PPM detects inaudible codes embedded in the audio portion of media and entertainment content delivered by broadcasters, content providers and distributors. At the end of the day, the meter is placed in a docking station that extracts the codes and sends them to a central computer. The PPM is equipped with a motion sensor, a patented quality control feature unique to the system, which allows Arbitron to confirm the compliance of the PPM survey participants every day.
