WCRB-FM Signs for Arbitron Portable People MeterTM Ratings Service in Boston

NEW YORK, January 3, 2007 – Arbitron Inc. (NYSE: ARB) announced today that WCRB-FM, Boston’s heritage classical radio station at 99.5 FM recently acquired by Nassau Broadcasting Partners, L.P., has entered into a multi-year agreement for Arbitron’s radio ratings services that include Portable People MeterTM audience measurement services when deployed in Boston.

Nassau’s Sr. Executive Vice President Tristram Collins commented, “WCRB is poised to enhance the value of our audiences in the eyes of our advertisers through PPM ratings. Advertisers and agencies are demanding a better way to buy radio with better data and more accountability for their investments. In signing for the PPM service in Boston, we can demonstrate to the decision-makers that radio can do an excellent job targeting the appropriate audiences.”

“We are pleased that WCRB has embraced the Portable People Meter as an investment in better measurement for radio,” said Carol Hanley, senior vice president, Sales, Arbitron. “We have worked hard to demonstrate that, for today and for the foreseeable future, the Portable People Meter is the ideal programming and sales tool."

The Portable People Meter, an electronic audience measurement technology that has been in U.S. market trials since 2001, is scheduled to be used in the top 50 markets in place of the current paper and pencil diary method that the company has employed to collect radio audience estimates since 1965.

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.

In its current form, the PPM detects inaudible codes embedded in the audio portion of media and entertainment content delivered by broadcasters, content providers and distributors. The company is field testing an enhanced version of the meter that can also collect audio signatures for any radio station, which are later matched to signatures collected by an in-market monitoring system.

At the end of the day, the meter is placed in a docking station that extracts the codes and signatures 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.
