Vistar Media

Leading full-stack programmatic DOOH platform, recognized as a pioneer in bringing automated, data-driven buying and selling to the out-of-home advertising industry

Vistar Media, now part of T-Mobile following a $600 million acquisition announced in January 2025, is a pioneering programmatic advertising platform specializing in digital out-of-home (DOOH) advertising technology. Founded in 2012, Vistar was built to bridge the gap between traditional outdoor advertising and modern programmatic capabilities, establishing itself as one of the most significant players in bringing data-driven, automated buying and selling to the DOOH ecosystem. The platform connects advertisers and agencies with an extensive network of digital screens spanning billboards, transit stations, airports, retail environments, and other out-of-home venues, enabling precise audience targeting at scale. Vistar's technology stack encompasses both a demand-side platform (DSP) for media buyers and a supply-side platform (SSP) for media owners, creating a full-stack marketplace that facilitates real-time programmatic transactions across thousands of digital screens globally. The company's data-driven approach leverages location intelligence, audience segmentation, and measurement capabilities to help advertisers reach consumers in the physical world with the same precision and accountability expected from digital advertising channels. This positions Vistar as a critical infrastructure layer within the rapidly growing DOOH market. T-Mobile's acquisition of Vistar Media signals a major strategic push by the telecom giant to expand its advertising business, combining Vistar's DOOH programmatic expertise with T-Mobile's rich first-party data assets and network reach. The deal underscores the growing convergence of telecommunications and advertising technology, and positions the combined entity to offer advertisers uniquely powerful cross-channel targeting capabilities. Vistar continues to operate as a distinct brand and platform within T-Mobile's advertising portfolio, serving brands, agencies, and out-of-home media owners worldwide.
