Nielsen Finds Irregularities In Los Angeles PPM Homes
August 22, 2016 at 12:41 PM (PT)
NIELSEN has informed L.A. audio clients that it has identified irregular compliance patterns in PPM homes in the LOS ANGELES metro area. An extensive investigation found that NIELSEN’s quality standards were not followed. It's official statement:
"As part of NIELSEN’s ongoing quality assurance program, we identified irregular patterns in select PPM homes in the LOS ANGELES metro area. Following an extensive investigation, we have determined that NIELSEN’s quality standards were not followed. Out of an abundance of caution, we removed 35 installed households, which collectively represented 55 average daily in-tab persons for the first two weeks of AUGUST. This accounts for 2% of the average daily in-tab in the LA metro area. Combined, the affected meters contributed less than 1% of the quarter hours of listening for these weeks. The AUGUST 2016 Week 3, Week 4, and monthly data releases will exclude these homes. The data will release as originally scheduled.
"We are conducting an impact analysis of 2016 data in LOS ANGELES 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. We are also investigating all other PPM markets and conducting an aggressive review of protocols and will be taking a number of steps to prevent recurrence. NIELSEN 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 cannot share any station-specific information on the irregularities; however, the preliminary analysis shows the tuning from these homes involved less than 1% of total listening for AUGUST Week 3. NIELSEN is also conducting impact analysis for prior months in 2016; this information is expected to be available early next week. Further analysis is still ongoing.
