Nielsen has given the heave-ho to 35 households participating in the Los Angeles PPM panel, after the ratings company identified “irregular compliance patterns in select PPM homes” in the metro area.
In a note sent August 22 to clients, Nielsen explained that it had conducted “an extensive investigation,” which determined that Nielsen’s quality standards were not followed.
“Out of an abundance of caution,” the households in question were removed. These households represented 55 average daily in-tab persons for the first two weeks of August.
This accounts for 2% of the average daily in-tab and contributed less than 1% of listening for these weeks, Nielsen says.
With the removal of the 55 average daily in-tab persons, the Nielsen PPM August 2016 Week 3, Week 4 and monthly data releases for Los Angeles will move forward as originally scheduled, Nielsen says.
Nielsen, however, is already conducting an impact analysis of 2016 data for the Los Angeles market to determine what, if any, actions may be required for prior months.
“We will be in constant communication with our Los Angeles clients to ensure they are kept updated on the results of the impact analysis and plans moving forward,” Nielsen says.
Furthermore, Nielsen is investigating every other market in which the Portable People Meter is used to provide radio listening and exposure estimates. “We are conducting an aggressive review of protocols and will be taking a number of steps to prevent recurrence,” Nielsen says, adding that it is committed “to upholding the highest standards of data integrity and market transparency in order to provide the most effective audience measurement solutions to meet client needs.”
Nielsen will continue to actively update clients and the industry on our findings and steps moving forward.
