As a result of settlements with the New York, New Jersey and Maryland Attorneys General, Nielsen is required to include a disclosure statement on all PPM data (both audience estimates and sample performance data), promotional, advertising, training and information materials. The notice also appears when using NRD or CSAR markets if the applied geography includes any PPM data. The disclosure must state:
PPM ratings are based on audience estimates and are the opinion of Nielsen and should not be relied on for precise accuracy or precise representativeness of a demographic or radio market.
