The Media Rating Council on Monday said that it reinstated the accreditation of Nielsen’s national television audience measurement (TAM) service, the system Nielsen is planning to replace with Nielsen One, its new multiplatform measurement system.
Nielsen lost the accreditation for its legacy system during the pandemic, when an inability to visit panel homes led to the sample size shrinking and Nielslen undercounting viewership. That added volume to complaints that Nielsen’s methodology was inadequate and antiquated as TV plunged into the streaming era.
