Our Watch segment provides media and advertising clients with independent measurement of the Total Audience across all screens, devices, and platforms consumers are using to access content. Nielsen's ratings are widely regarded as the
currency in the media buying and selling marketplace. Beyond ratings, Nielsen's Watch portfolio provides analytics that help clients to understand the reach of (how many and who did my ad reach?), resonance of (does it change how they think?), and reaction to (does it change how they buy?) advertising.
