NEW YORK -- Linda Dupree Retains Responsibility for "Project Apollo" as Senior Vice President, Portable People Meter, New Product Development

Arbitron Inc. (NYSE: ARB) announced today that the company is reorganizing the responsibilities of two key executives in order to speed the commercialization of the Portable People Meter (PPM(SM)) audience measurement system.

"In 2006, we will be taking our Portable People Meter system from a stand-alone development effort to an integral component of our core media services," said Steve Morris, president and chief executive officer, Arbitron Inc. "To bring PPM to the U.S. media marketplace as quickly as possible, we must make changes to our organization while delivering the best of new and traditional services to our customers. The solutions require closely integrating operations, technology and research and development into a tightly knit team capable of accelerating our speed to market with next generation versions of our traditional tools."

Owen Charlebois has been appointed president, Operations, Technology, Research and Development. The business unit he heads will deploy Arbitron's Portable People Meter-based audience measurement services as well as operate Arbitron's existing radio audience measurement services. Mr. Charlebois will be responsible for continuing the company's efforts to enhance the quality of the diary-based radio ratings as Arbitron begins the transition to electronic measurement.

Pierre Bouvard has been appointed president, Sales and Marketing. Mr. Bouvard assumes responsibility for all of Arbitron's sales and marketing efforts, both for the Portable People Meter and for Arbitron's core services. The company's core services include network and local market radio ratings, national and local market consumer research, outdoor and cable research services, software for media and marketing analysis, custom research and online radio ratings. Mr. Bouvard will also oversee Arbitron's marketing efforts in Mexico, Canada and in other international markets.

Linda Dupree, senior vice president, Portable People Meter New Product Development, continues to oversee the development of market research services based on the Portable People Meter technology. She is currently heading up Arbitron's contribution to "Project Apollo" the joint effort with VNU to explore the possible development of a new, national marketing research service which would use the Portable People Meter and in-home scanners along with other technologies to collect multi-media and purchase information from a common sample of consumers. Ms. Dupree continues to report to Steve Morris.

Owen Charlebois was previously president, U.S. Media Services for Arbitron, joining the company in January 2001. He was formerly president and chief executive officer of BBM Bureau of Measurement, the Canadian radio and television ratings consortium.

Prior to joining BBM in 1990, Owen was a senior executive of the Gallup Organization in Canada, from 1987 through 1990. In his last two years at Gallup, Owen was president, responsible for all of Gallup's Canadian operations.

Mr. Bouvard previously was president, Portable People Meters and International, having been appointed in January 2005. Pierre has also been president, Webcast Services and New Ventures, and vice president and general manager for Worldwide Media Information Services.

Pierre has served Arbitron in various sales and management capacities, rising from client service representative to manager in the Chicago, San Francisco, New York and Dallas offices. He left Arbitron for a five-year period, when he was executive vice president of Coleman Research, one of the premier strategic consulting firms for radio stations.

About the Portable People Meter

The Arbitron Portable People Meter (PPM) 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.
