GSTV, the video ad network broadcasting to **170 million monthly viewers** at U.S. gas pumps, integrated Stagwell's agentic AI system to sharpen audience targeting and improve how brands match physical products to shoppers in real time, according to Marketing Dive. The system analyzes behavioral, location, and transaction data to segment audiences at the station level, then dynamically adjusts creative and product messaging to fit the audience filling up at that moment.

The mechanics: GSTV feeds its network data into Stagwell's AI agent, which processes viewership patterns, local demographics, time-of-day behavior, and purchase intent signals. The agent then clusters audiences into high-value segments and pushes specific creative to screens at stations where those clusters concentrate. A CPG brand selling premium pet food, for instance, can now serve ads at stations in neighborhoods with above-average pet ownership and disposable income, rather than blanket the network. The system runs continuously, refining segments as fresh data arrives, and adjusts the media buy in near real time.

The underlying mechanism is contextual retail media applied to physical space. Gas stations sit at a rare intersection: high dwell time (the average fill-up lasts **4-5 minutes**, enough for a video ad to register), captive attention, and proximity to convenience stores where impulse purchases happen. By layering AI-driven segmentation onto that environment, GSTV turns what was once a broadcast medium into a targeted one. The advertiser pays for reach that correlates with buyer intent, not just eyeballs. Media efficiency improves because waste drops—fewer ads served to audiences with no propensity to buy.

For a small physical-product brand, the steal is this: find a retail media channel with high dwell time and transaction proximity, then use behavioral or location data to refine your audience before you buy the placement. If you sell a niche consumable—say, cold brew coffee or single-serve protein snacks—look for convenience-store networks or micro-retail screens that allow geo-targeting or daypart buys. Contact the network operator and ask for audience segment data: time of day, ZIP overlay, category purchase history. Negotiate a test buy against a single high-propensity segment (morning commuters in affluent suburbs, for example) rather than a network-wide flight. Budget **$2,000–$5,000** for a two-week test. Track in-store lift at the nearest retail partner to validate the targeting. The play scales when you prove the segment converts.

The broader pattern: as out-of-home ad networks digitize, they inherit the targeting tools that online retail media built. Physical-product brands no longer need broadcast budgets to reach shoppers in physical space. They need data and a hypothesis about where their buyer is, at what moment, and how much dwell time the medium offers. GSTV's move confirms that agentic AI accelerates this shift, but the core advantage is accessible to any brand willing to trade reach for relevance and measure the result.

## The takeaway

Target physical-world ads by audience segment and proximity to purchase, not blanket reach—GSTV proved it lifts efficiency.
