T-Mobile Makes Mobile Data Exclusive to Vistar for DOOH Targeting
T-Mobile Advertising Solutions announced that its mobile data is now exclusively available for out-of-home (OOH) campaign targeting via Vistar Media, which T-Mobile acquired in January 2025. Advertisers can use Vistar to activate off-the-shelf and custom audiences built on T-Mobile's first-party data, including mobile location data and anonymized app usage data. This integration brings in-app targeting capabilities to DOOH. T-Mobile is also experimenting with agentic AI tools and self-serve solutions for audience building, and plans to offer DOOH measurement capabilities next year. The exclusive arrangement is partly driven by tightening regulations around location data, making it safer to share data only with its owned platform.
This announcement strengthens the DOOH ad ecosystem by integrating carrier-grade first-party mobile data into a major OOH SSP, potentially increasing programmatic DOOH adoption and bringing new measurement capabilities. It also highlights the strategic value of T-Mobile's vertical integration in ad tech.

Vistar Media's Kevin Smyth on Programmatic DOOH Challenges
In an interview with ExchangeWire, Kevin Smyth, Managing Director EMEA at Vistar Media, discusses the state of programmatic Digital Out-of-Home (DOOH).

Smyth also highlights the growth of programmatic DOOH, the importance of measurement standards, and the potential of CTV convergence. He stresses that the industry must move beyond traditional OOH buying mindsets and embrace the programmatic ecosystem to unlock its full potential.
DOOH Store Locator Position Study Shows Top and Bottom Perform
A study by Vistar Media, Omnicom Media, and Annalect examined the optimal placement of store locator information in dynamic DOOH creatives. Testing 7,200 participants in the Netherlands, the study found that placing the store locator at the top of the creative increased purchase intent by 20%, while bottom placement boosted visit intent by 9%. The middle position underperformed on both metrics. Category-specific results showed significant lifts for retailers and confectionery brands. The study also highlighted the importance of design elements like pin icons and contrast, and cautioned against prominent retailer branding that could reduce brand recall for advertisers.
