The Radio Research Consortium (RRC) is a non-profit research company based in Olney, Maryland which provides listener data on radio audiences to non-commercial stations in the United States.
The company made it possible for public radio stations to show advertisers and underwriters that they commanded a much larger share of the market than previously assumed.
[3] In the case of the San Francisco Market, for example, KQED-FM actually ranked 2nd or 3rd in 2005-2006 but was absent from traditional reporting of Arbitron data in publications such as Radio & Records which include only commercial stations.
[1] RRC's founding employees include former Arbitron Employees including the former Manager of Production and Radio Market Reports.
[4][5] RRC has been criticized for contributing to the homogenization of public radio, particularly in their home market, Washington DC.
