Media Professional Plus is a new national and regional radio audience information service from Arbitron. It offers access to audience info from Arbitron U.S. markets. It lets advertisers and agencies create custom geographies and trade areas using radio Metro, DMA and county information. It also provides data on a trading area’s CPP so groups can place more efficient media buys. The data is accessed using the Media Professional 9.0 software used for Arbitron’s respondent local market radio audience information service. The data sets will be released semi-annually after the spring and fall releases for local markets.
