The additional tools expand on the existing local TV measurement agreement between Nielsen and NBCUniversal.

Nielsen’s Rhiza tools are used by local TV sales teams and researchers to visualise their insights and explore analytics by market, sector and audience. The tool includes data from Nielsen Scarborough and Polk Automotive.

The voter ratings cross-platform tool provides stations with monthly data on all voter and viewer types, offering insights on voters’ media consumption behaviour based on race, gender and demographic data.

Frank Comerford, chief revenue officer and president of commercial operations, NBCUniversal Owned Television Stations, said: “Nielsen’s consumer and voter ratings tools are welcome additions to the already robust measurement toolkit we've created for our stations, which is helping us create a clear snapshot of the value and reach our NBC and Telemundo stations have with advertisers and consumers.”
