More Than 239 Million Listen to Radio Every Week According to the Arbitron RADAR 105 Report

COLUMBIA, MD; June 15, 2010 – Radio reaches more than 239 million Persons aged 12 and older over the course of a typical week, according to the RADAR® 105 National Radio Listening Report, which releases Monday, June 21, 2010.

The combination of PPM and diary respondents have shown more listeners to radio over the course of a week versus the 2007 RADAR listening reports which were based on diary respondents alone.

Over the course of a typical week, nearly 220 million Persons aged 12 and older tune to more than 7,200 RADAR Network Affiliated stations, up from 213 million listeners one year ago in RADAR 101.
