Media Rating Council Revokes Accreditation for Nielsen’s PPM Service in Four Markets
Last Friday (10/16), the Media Rating Council released its quarterly accreditation report for the numerous media rating services and in it revoked the accreditation for Nielsen’s Audio 
PPM service in the Baltimore, Jacksonville, Philadelphia and Pittsburgh markets. Additionally, the MRC denied accreditation for the Audio PPM service in 18 markets including Austin, Baltimore, Boston, Dallas, Hartford, Houston, Jacksonville, Las Vegas, Memphis, Nashville, New York, Norfolk, Orlando, Philadelphia, Pittsburgh, Providence, Raleigh, Sacramento, San Francisco, Seattle, Washington DC, and West Palm Beach. This does not mean that Nielsen cannot continue to market the service; the PPM ratings in the above markets will lose their “audited” label. As in the past when accreditation is revoked or denied, Nielsen says it is working to improve the measurement systems.
