Nielsen to fold co-viewing into currency ratings for 2026-27 TV season

Nielsen announced on 19 August 2026 that co-viewing — multiple people watching the same screen together — will enter its currency ratings, the figures ad buyers and sellers transact on, for the 2026-27 US TV season. A February pilot across Super Bowl LX, the Olympics Opening Ceremony and the NBA All-Star Game found a 4.19% average viewership lift. The Video Advertising Bureau has warned the data could be inconsistent.
