Retail just bought the billboard

The World Out of Home Organisation released its first Global pDOOH Expenditure Study this month. Retail is the biggest advertiser vertical in global programmatic digital out-of-home: $165 million in 2025, 12.4% of total spend. Finance is right behind at $161 million. A first-of-its-kind global study, a clear vertical leader, and a runner-up only $4 million behind: this is the baseline the industry will be measured against from here on.

What the headline numbers say

Start with the shape of the leaderboard. Retail at $165 million and 12.4% of total programmatic DOOH spend, finance at $161 million just behind. The gap between first and second is $4 million on a $1.4 billion base, which is essentially a tie with a narrative. Two verticals with very different businesses have both decided, independently and at scale, that buying digital screens programmatically is worth nine figures.

That convergence is the real headline. Retail and finance do not buy media for the same reasons. Retailers buy proximity to stores and foot traffic; financial brands buy trust, presence, and mass awareness in high-traffic environments. When both land at the top of the same programmatic channel, the signal is about the channel, not the vertical. Programmatic DOOH has crossed from experimental budget to strategic budget for the categories with the most to lose from getting media wrong.

And because this is WOO's first global study, these numbers are the baseline, not the trend. Every future edition will be read against $165 million, 12.4%, and $1.4 billion. First editions matter because they convert anecdote into benchmark. From here on, "programmatic DOOH is growing" is a claim you check against the study, not a vibe you assert in a pitch deck.

Programmatic DOOH grows up

Total global programmatic DOOH hit $1.4 billion in 2025, and 34.5% of it already flows through omni-channel DSPs. Programmatic DOOH isn't a side experiment anymore; it's being folded into cross-channel buys, planned and measured alongside everything else. The 34.5% figure is the maturity metric. More than a third of programmatic DOOH spend now moves through the same demand-side platforms buyers use for display, video, and audio.

That matters for three reasons. First, planning: when OOH sits in the same platform as everything else, it gets planned against the same audiences and the same objectives instead of in a silo. Second, measurement: unified platforms mean unified reporting, which means DOOH starts getting judged on the same outcomes as the rest of the mix. Third, access: buyers who already have DSP seats can add screens without new vendors, new contracts, or new workflows. The friction that kept DOOH separate is dissolving, and the 34.5% tells you how far along that process already is.

Why retail leads

Retail's $165 million lead is not an accident; it is the vertical whose business model maps most directly onto what screens do. Retailers live and die on traffic through doors. Screens near stores, screens on the commute past stores, screens in the shopping district: the medium is a proximity machine, and retail is a proximity business. Programmatic adds the layer retail actually needed: the ability to buy those screens with the same audience logic, dayparting, and measurement discipline it already applies to digital.

There is also a testing logic to retail's early lead. Retailers run thousands of locations and measure everything against store-level outcomes, which makes them fast learners. A channel that can be bought programmatically, tested in a few markets, and measured against foot traffic or sales lift fits the retail experimentation playbook perfectly. Retail did not lead because it loves billboards. It led because the channel finally became testable, and retailers test everything.

Keep the scale honest

Honest caveat: that's programmatic DOOH only, about 7% of all DOOH spend. Most inventory still trades the old way. The $1.4 billion is real money and real growth, but it sits inside a much larger traditional market where deals are still done the way they have been done for decades: direct buys, long-term contracts, relationship sales.

The arithmetic is worth stating plainly. If programmatic is about 7% of all DOOH, then roughly 93% of the world's digital out-of-home still trades traditionally. That is not a weakness in the story; it is the story. A channel at 7% programmatic penetration with retail and finance already spending nine figures each is a channel early in its adoption curve, not late. The trend is real but the base is small, which is exactly when smart buyers get in: while inventory is available, auction pressure is low, and the learning is cheap.

Why a small base is the entry window

Counterpoint to the excitement, and it cuts in the buyer's favor. When 93% of inventory still trades the old way, programmatic buyers are fishing in a lightly contested pond. Less competition in the auction means better prices and better placements for early movers. The brands that build programmatic DOOH competency now, while the channel is small, will be the sophisticated buyers when the channel is large.

Retail's $165 million is best read as an early-mover signal, not a mature-market verdict. The vertical with the sharpest measurement culture looked at programmatic screens and put nine figures behind them. That does not mean every brand should match retail's spend. It means the testing window is open, the benchmarks now exist, and waiting until programmatic DOOH is obvious means waiting until it is expensive.

The retail copycat playbook

1. Start with one market and one objective. Store visits, local awareness, or event support. One market keeps the test cheap; one objective keeps the read clean.
2. Buy through the DSP you already use for other channels. That is what the 34.5% is telling you: the buyers getting value from programmatic DOOH are planning it alongside everything else, in the same seat, against the same audiences.
3. Build creative for the medium. Screens get seconds of attention at distance. Short copy, high contrast, one idea per placement. Do not shrink a digital banner and call it an out-of-home strategy.
4. Measure like you mean it. Foot traffic lift, store sales in exposed markets, brand awareness deltas. Judge the test on business outcomes, the same standard the rest of your mix faces.
5. Scale on evidence, not enthusiasm. If the test market shows lift, expand to the next tier of markets. If it does not, you spent test money to learn something real, which is the entire point of the 7% window.

Read the study like an analyst

First editions deserve a careful read. Methodology settles over time, definitions of what counts as programmatic vary by market, and 2025 figures are estimates built on the data WOO could assemble. None of that invalidates the study; it just means you should treat this edition as the baseline and watch the trend across future editions rather than overreading any single number.

The numbers to anchor on are the structural ones: retail at $165 million and 12.4%, finance at $161 million, $1.4 billion total, 34.5% through omni-channel DSPs, and programmatic at about 7% of all DOOH. If future editions show the 7% climbing and the $1.4 billion compounding, the thesis holds. If retail's share holds while the base grows, the vertical leadership story holds. Benchmarks are only useful if you revisit them, so put a reminder on the calendar for the next edition.

If retail is buying screens programmatically at this pace, the question is whether your brand is on them.
