Nielsen

Nielsen measures how people consume television, streaming, digital and audio content and advertising. Its ratings and cross-media measurement products, including Nielsen ONE, combine panels with big data from set-top boxes, smart TVs and digital sources to give publishers, broadcasters, agencies and advertisers deduplicated audience figures used to plan and trade media. Ad Intel tracks advertising occurrences and spend across channels for competitive analysis, while digital ratings products measure online content and campaign audiences. Through Gracenote, Nielsen supplies metadata and identifiers for video, music, sports and podcasts that streaming services and device makers use for search, recommendations and program guides. The company also offers media planning and marketing outcome tools and operates in dozens of countries.
