Arbitron Inc. announced today that it has purchased the RADAR radio network audience measurement service of Statistical Research Inc. (SRI), Westfield, New Jersey, for $25 million.

RADAR (Radio's All Dimension Audience Research) is a national radio ratings service that measures audiences to radio commercials aired on 29 radio networks operated by ABC, American Urban Radio Networks, Premiere and Westwood One. The service produces its estimates using a 12-month, 12,000-person telephone survey in combination with the industry-standard commercial clearance system.

"We plan to use a subset of our local market diaries to dramatically increase the sample size for the RADAR network survey," said David Lapovsky, EVP of Worldwide Research at Arbitron. "By combining our two services, Arbitron can provide the industry what would have been economically impractical for RADAR to provide on its own - network audience estimates of greater utility and flexibility."

Arbitron surveys more than 1.3 million radio listeners in more than 3,500 counties across the United States in the course of its local market radio ratings surveys in 286 markets throughout the year.
