Panel

Also: Measurement panel

A recruited sample of people whose media consumption is recorded and projected to the population: Nielsen's TV panel, Comscore's digital panel, YouGov's brand tracking panel. Panels are the only way to measure across walled gardens without their cooperation, and they are small relative to digital audiences.
