Nielsen Fixing PPM Disconnect

NielsenAudio notified PPM clients Thursday of a lost of connectivity with some of its Peronal People Meters. The loss affected 8% of the installed devices affecting week one of (11/3-11/9) of the upcoming December 2016 Survey.

The company blamed the outtage on moving to a new audio data collection site.  It assured clients that the lower in-tab doesn't equate to lower ratings.   However, temporarily higher weights may contribute to more variation during the period of time it takes for these panelist to be back in-tab and fully accounted for.

Media Confidential has obtained a copy of the client notice:
As the result of a move to a new audio data collection site last weekend, we discovered that 8% of the installed PPMs across the aggregate of 48 PPM markets lost connectivity and became inactive. This connectivity issue began in week one (11/3-11/9) of the December PPM monthly survey.  
Our Panel Relations Specialists have already been in contact with these homes and all affected panelists have now been sent new PPM devices. As of today, 49% of the replacement meters are back online. We expect the balance to come online in the next several days.  
We forecast the percentage of installed and fully operational meters eligible for in tab will be 97% for the month of December and 92% for week one of December across the aggregate of markets. Weighting will adjust for demographic and geographic imbalances. Therefore, buyers and sellers will be able to transact business with confidence. Please note that lower in-tab doesn't equate to lower ratings. However, temporarily higher weights may contribute to more variation during the period of time it takes for these panelist to be back in-tab and fully accounted for. 
 Nielsen is conducting an analysis to evaluate panel representation and impact to audience estimates. We will share the results of this analysis with you during the week of November 21, prior to the delivery of the Weeklies data for week one of December.  
Your Nielsen Client Solutions representative will contact you to review what this means for your market. We will be sure to keep you updated on our progress as we work to bring these panelists back online.
