New York - Jan 23, 2008 - Entercom Communications has signed a multi-year contract for Arbitron Portable People Meter radio ratings services. The agreement takes effect as the new audience ratings technology is commercialized in each of 14 markets encompassed in Arbitron's current PPM rollout plan: Austin, TX; Boston; Denver; Greensboro-Winston Salem-High Point, NC; Indianapolis; Kansas City, MO; Memphis, TN; Milwaukee, WI; Norfolk, PA; Portland, OR; Providence, RI; Sacramento, CA; San Francisco and Seattle.

The agreement covers all 64 stations owned by Entercom in the radio markets scheduled to convert to PPM measurement by the end of 2010. Over the next three years, Arbitron is scheduled to deploy the Portable People Meter in the top 50 markets in place of the paper diary method that the company has used to collect radio audience estimates since 1965.
