Disney Advertising, which owns ESPN and other outlets, recently held an unusual three-hour closed-door meeting with Nielsen executives, spanning key players from across industry segments, to discuss concerns about the accuracy of live sports ratings.
Executives from NBC Universal, Paramount, Amazon, Google, and Apple, as well as the NFL, NBA, and NHL sports leagues, and agencies including Omnicom Media Group, Publicis Media, and WPP's GroupM, also attended the meeting.
The disparities between Nielsen data and other measurement providers were closely scrutinised in the meeting.
According to one of the meeting attendees, the issues discussed included ensuring consistency and transparency across media companies, as well as increasing the scale of measurement coverage and reliability.
As demanded by some meeting participants, Nielsen agreed to provide more details on how it will handle co-viewing and out-of-home measurement in follow-up meetings.
