Nielsen folds PPM wearable co-viewing data into currency ratings August 31

Starting August 31, Nielsen will incorporate signals from wrist-worn Portable People Meter devices into its co-viewing data, moving passive audio-based detection from a February pilot into currency-grade audience measurement ahead of the fall TV season. The PPM wearables, deployed nationally since 2016, listen for embedded TV audio without requiring panelists to log in, sidestepping a known blind spot in multi-person households.
