Karthik Rao

Karthik Rao is the Chief Executive Officer of Nielsen, the global leader in audience measurement, data, and analytics. He assumed the CEO role in 2024, taking the helm of a company undergoing one of the most significant transformations in its century-long history — navigating the shift from traditional linear TV measurement to cross-platform, streaming-inclusive audience metrics. His leadership is central to Nielsen's push to establish its Big Data + Panel methodology as the industry standard for a fragmented media landscape. Rao spent the bulk of his career rising through the ranks at Nielsen, accumulating deep expertise across the company's measurement, media, and data science divisions. Before becoming CEO, he served as President of Nielsen, overseeing core operational and strategic functions. His tenure has been defined by efforts to modernize Nielsen's measurement infrastructure, including the development of Nielsen ONE, the company's unified cross-media measurement solution designed to give advertisers and media owners a single, deduplicated view of audiences across linear TV, streaming, and digital platforms. In the AdTech and media measurement ecosystem, Rao is a significant figure because Nielsen's methodologies directly influence how billions of dollars in advertising inventory are bought and sold. His work on cross-media measurement standards places him at the intersection of traditional media, streaming, and programmatic advertising, making him a key voice in industry debates around currency, identity, and audience verification.
