The same day that Nielsen revealed its figures have been off since March due to a technical error, the company met with representatives of stations in New York to hear complaints about an apparently unrelated issue — concerns among the broadcasters that their aggregate 25-54 demo ratings for June were down 20% from a year ago, TVNewsCheck reports.

“The ratings firm met last Friday with representatives of New York City stations to explain how it plans to improve the ratings by increasing the sample homes and perhaps deploying new PPM technology that [makes] use of program audio to track what people are watching,” the story reports.

The stations reportedly lost a combined 2,250 ratings points from a year ago in 25-54, creating a huge loss of revenue. Nielsen did not promise to reissue any numbers, the piece reports, citing a broadcaster who was at the meeting.

In a statement issued after Friday’s meeting, Nielsen said: “Capturing a representative measurement of how consumers are viewing video across all types of platforms is the No. 1 priority for Nielsen. We are increasing our sample sizes and have announced 60 markets thus far — including New York — where we are adding tablet and smartphone viewing of local TV content to the ratings, and actively evaluating big data sources to add greater stability.

“We are also testing the inclusion of out-of-home viewing, and more granular qualitative data to the mix. The viewing pie is expanding and our goal is to ensure that the ratings pie grows, as well.”

The statement did not address any specific complaints about lower ratings for the New York stations, the report points out.
