In a memo sent to client stations today, Nielsen announced that it will no longer expire PPM Panel homes at approximately 2 years.
Instead, Nielsen will stretch the panel time to 32 to 38 months. Nielsen does not proactively disclose to panelists that their maximum tenure is 2 years, but their tenure is internally tracked and Nielsen expires homes as they near the 2 year mark. Nielsen says that recent analysis shows that about 36% of panelists reach their full tenure. The change will take effect for all new installations as well as for existing homes that reach 2 years post August 12, 2025.
The full memo reads:
In the PPM Panel today, Nielsen typically expires homes approximately 2 years after they join the panel, ranging from 20-26 months. There have been exceptions to this practice, such as during COVID and in some cases at the individual market level. While Nielsen does not proactively disclose to panelists that their maximum tenure is 2 years, the PPM Panel tenure is internally tracked and Nielsen expires homes as they near the 2 year mark. Recent analysis shows that about 36% of panelists reach their full tenure.
Beginning August 12, 2025, Nielsen will no longer expire PPM Panel homes at approximately 2 years but instead will allow homes to remain in the PPM panel for approximately 3 years, ranging from 32 – 38 months. This will be true for all new installations as well as for existing homes that reach 2 years post August 12, 2025.
Nielsen remains focused on maintaining the size and improving proportionality in the PPM panel. Due to a variety of factors, we are finding that the time required to recruit a new home has increased. As a result, we have seen fluctuations in our panel size. This change will enable more flexibility in the expiration schedule and create less overall churn.
Reducing churn in the panel will help to stabilize installation counts and also enable resources to focus more time on the hard to reach demographics that tend to turn over at a higher rate than other demographics.It is important to note that there are rigorous compliance rules executed daily in the PPM panel to ensure that panelists are complying with the various carry and compliance requirements. Homes that are found to be non-compliant are coached and if compliance does not improve to meet the defined rules, the home is removed from the sample, irrespective of their tenure. These compliance rules and removals will continue to be applied to homes throughout their tenure in the PPM panel.
Nielsen does not believe this change will have a material impact on listening levels, as analyses have shown that listening levels do not vary significantly by length of time in panel when controlling for demographic and market differences. As Nielsen is committed to the MRC process, we reviewed the results with the MRC Audio Committee and received approval to proceed with implementation. This approval came with a few conditions regarding post-deployment monitoring. Panelists will be continuously monitored to ensure compliance and these compliance rules are independent of listening levels. In addition, Nielsen will be monitoring panel KPIs such as panel size (DDI) and representation (proportionalitv) and will be implementina auardrails at which Nielsen will take corrective action. Nielsen will repeat the analvsis on listenina analvsis approximatelv 2-3 months
I understand that this is really all this Nielsen can do with response rates being terrible already and likely to become even worse. But in practical application, if you get a household of hot meters in a highly weighted demo, you’re golden for 3 years. Or if you’re a competitor, you’re screwed for 3 years. I can’t think this move will lead to more accurate ratings but again, it’s all Nielsen will do as long as the industry allows them to be in the media measurement business.
