The Media Rating Council (MRC) has revoked accreditation for Nielsen Audio’s Portable People Meter (PPM) service in four markets: Baltimore, Maryland; Jacksonville, Florida; Philadelphia, Pennsylvania; and Pittsburgh, Pennsylvania.
The council also denied accreditation for 18 markets that were already unaccredited. Its quarterly report, released October 16, identifies the actions as September decisions.
What the disclosure establishes
The report lists the affected services and decisions but does not explain the specific deficiencies behind the radio-market actions. It does not announce that Nielsen has stopped producing those ratings.
The distinction matters for stations, agencies and advertisers assessing the measurement used in local advertising transactions. A market-specific accreditation decision should not be described as a blanket invalidation of Nielsen’s radio or television services.
Questions for buyers and stations
The next reporting questions are what corrective work is required, when each market might be reconsidered and how agencies will handle accreditation disclosures in their buying decisions. The council’s summary does not provide that timetable.
