Arbitron Responds to GAO Inquiry of PPM

COLUMBIA, Md.; July 28 /PRNewswire-FirstCall/ -- Arbitron Inc. (NYSE:ARB) has released the following statement

"According to the website of the U.S. House of Representatives
Committee on the Judiciary, a group of ten members of Congress have
requested that the Government Accountability Office study the
Arbitron Portable People Meter(TM) and its "effect on advertising
revenue streams for radio stations." Arbitron is and will continue
to monitor the situation.

"As always, Arbitron welcomes every opportunity to discuss the PPM
technology, service and our sampling methodology. We continue to
have a dialogue with key members of Congress as well as other
interested parties, and look forward to helping the radio industry
as a whole remain competitive in the current media marketplace."

The PPM radio audience estimates are currently used as the basis for buy/sell transactions of radio commercial time among subscribing stations, agencies and advertisers in 20 major U.S. markets.

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 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.
