Our Story

Our Name

How does a brand with more than 140 years under its belt invent the new normal? Considering our past and addressing the present, we took great care in building a new kind of advertising company that leads with curiosity and courage as we move toward the future.

Looking ahead requires an understanding of what came before.

We took to the archives to reconnect with our roots,  reintroducing ourselves to Alexander Graham Bell — the inventor and pioneer — to ask who he might be if he were empowered with the tools and technology of today.

The name ‘Xandr’ reflects our entrepreneurial spirit and dedication to using our history of innovation as the roadmap for propelling an industry forward.

A Look Back

Xandr started as a collective of legacies and passions aligned behind the mission of making advertising better. From the former AppNexus marketplace and enterprise technology, AT&T’s global distribution and customer reach, and the unparalleled portfolio of owned content across AT&T and WarnerMedia, we’ve joined together to move the industry forward and change what advertising means for consumers and companies. The connections we make through advertising fund award-winning journalism, music, video, and games-all at little or no cost to the consumers who enjoy open access to this premium content.

How Far We’ve Come

Since the launch of Xandr in September 2018 at the company’s marquee industry thought leadership event, the Relevance Conference, Xandr has been committed to its purpose to make advertising better for advertisers, publishers and consumers by building real solutions to move the advertising industry forward. In its first year as AT&T’s advertising company, Xandr launched numerous flagship products, including the premium video marketplace Community, strategic buying platform Xandr Invest and its strategic selling platform Xandr Monetize. One year later, Xandr revealed the next evolution of Xandr Invest, enhanced for the future of TV by allowing advertisers to activate audiences — and unique data insights — across multiple programmers.

From the start, Xandr has produced thought leadership based on AT&T’s unique consumer insights and original research studies, including the Relevance Report, Entertainment Discovery and TV Tune-In trends, and insights on Political Relevance in advertising. Xandr is equally committed to company culture and improving society as a whole. In 2020, WarnerMedia and Xandr combined to create a stronger value proposition for agencies, advertisers, and publishers.
