Nielsen has received accreditation for its Big Data + Panel national TV measurement from the Media Rating Council (MRC), certifying its ability to combine first-party viewership data with its panel. Why it matters: The certification better positions Nielsen to accurately capture viewership for TV networks and advertisers after the rise of media fragmentation and streaming challenged its traditional methods.

One of Nielsen’s newest audience-measurement products has won accreditation from the Media Rating Council, setting up a new option for advertisers at a moment when the media-tabulation giant has beebn facing competition from a group of upstarts and rivals.

The Media Rating Council approves the company's use of traditional panel sampling alongside input from millions more homes.
