He will oversee the existing ad-sales research team, as well as working with technology teams that are already in place.

Mazumdar will report to Marianne Gambelli, president of advertising sales for Fox Corp.

She said in a statement: “We know that a clear, data-powered, platform-wide approach to monetize at scale will serve our clients, and our business, in the most meaningful way,” adding that Mazumdar’s “wealth of expertise” in data science, research and analytics will be important to Fox.

Mazumdar was formerly chief data and research officer at Nielsen -- most recently working on audience identity efforts and the upcoming Nielsen One measurement platform.

Earlier this year Nielsen confirmed an undisclosed level of global layoffs -- this coming amid massive changes that are expected to come in media measurement, and a slowing economy. In October 2022, Nielsen Holdings closed sale, an all-cash transaction of $16 billion, including the assumption of debt, to a private equity consortium led by Evergreen Coast Capital/Brookfield Business Partners.

Before Nielsen, Mazumdar was the chief science officer at Simulmedia, responsible for data-driven targeting algorithms, and prior to that was chief strategy officer at market research company GfK.

Mazumdar started his career at advertising-technology company Google’s DoubleClick.
