Arbitron next week will release the complete RADAR 72 Radio Network Audience Report. Radio's All Dimension Audience Research (RADAR), which is released quarterly, measures audiences for radio commercials aired on the 31 individual radio networks operated by ABC Radio Networks, American Urban Radio Network, Clear Channel Communications' Premiere Radio Networks and Viacom-owned Infinity's Westwood One.

Results are based on telephone surveys of 12,000 Americans over the age of 12 throughout the country from January 2001 through January 2002.
