Nielsen and Acxiom Collaborate to Bring Increased Connectivity to Advanced Audiences

First of its kind ID-based, advanced audience integration

NEW YORK - March 27, 2025 - Nielsen, a global leader in audience measurement, data and analytics, has announced a new collaboration with Acxiom, the connected data and technology foundation for the world's leading brands and agencies. Nielsen will sync the Acxiom Real ID into the Nielsen ID system so that agencies and marketers can seamlessly leverage their Real ID audiences in Nielsen ONE for cross-platform and data-driven linear media.

The integration between Acxiom Real ID and Nielsen is an industry first. IPG marketers and agencies can now identify, reach, measure, and optimize messaging and media experiences to the audiences that matter most with scale and precision at the audience level.

As the media marketing industry continues to mature, modern marketers require the ability to fluidly execute and measure their marketing investments against real people across all platforms and channels. For too long, marketers have been forced to accept flawed metrics-clicks that don't relate to incremental sales or brand effects, bots that mimic engagement, and partner-by-partner measurement that cannot be deduplicated or actioned at scale efficiently. With Nielsen ONE and Acxiom Real ID, modern marketers now have a data-driven approach to identify, plan, measure, and optimize media and messaging against real people, not proxies, said Keith Camoosa, Chief Product and Technology Innovation Officer at Acxiom.

The integration with Nielsen ONE further allows Acxiom clients to securely put their first-party data assets to work at scale in media for brand, acquisition, and loyalty marketing while continuing to use their preferred methods for data connectivity and technology of choice.

Modern marketers are focused on increasing mental availability of their brands, and that starts with reaching the right audience. We're excited to bring this new integration to life with Acxiom so advertisers can more effectively plan and measure what audiences their campaigns reach, said Matt Devitt, Head of Advertisers and Agencies at Nielsen. As we continue to innovate our holistic Advanced Audience offerings for the marketplace, identity integrations with ecosystem partners like Acxiom are critical for bringing marketers the capabilities they need to deliver on their growth targets.

This announcement builds on Nielsen's momentum in innovation and collaborating with the industry to bring enhanced interoperability and simplicity to media buying and selling. Nielsen's solutions are underpinned by Nielsen's ID System as well as person-level data from industry-leading panels and backed by the scale of the industry's largest big data footprint and broadest coverage across digital, streaming, and CTV.
