German Retail Media at Three: Big Promise, Growing Impatience
TL;DR: Three years into Germany's retail-media boom, advertisers are still expanding budgets but are increasingly demanding real improvements in measurement, standards and usability, as early enthusiasm gives way to harder questions.
Where retail media stands
Retail media — advertising sold by retailers against their shopper data and inventory — has been the industry's hottest growth story, but three years in, German advertisers' patience is being tested, according to Horizont. Spend continues to rise, yet so does the demand for retailers to actually deliver on the promise.
The gripes are familiar: inconsistent measurement, walled gardens that are hard to compare, clunky buying, and a sense that some networks are better at selling inventory than proving results. Enthusiasm is maturing into scrutiny.
Why the honeymoon is ending
Every hot channel goes through this cycle: land-grab, then reckoning. Advertisers pile in on the promise, then start asking the hard questions about incrementality, standards and whether the numbers stand up. Retail media has reached the reckoning stage.
That is healthy, not fatal. The pressure forces retailers to professionalise — to adopt common measurement, self-service tools and transparency — which is exactly what turns a hyped channel into durable infrastructure.
The Marketing Minute read
Retail media isn't going away; it is growing up. The winners will be the retailers that respond to the skepticism by fixing measurement and usability rather than leaning on their data monopoly to keep selling.
For advertisers, the moment calls for discipline. Retail media can be genuinely powerful — closest to the point of purchase, rich in first-party data — but only if you demand proof of incrementality rather than accepting attributed sales at face value.
What businesses can take from it
When you buy retail media, insist on incrementality, not just attribution. A sale claimed by a retail network may well have happened anyway; the question that matters is what the ad actually added.
And treat every hot channel's honeymoon with healthy skepticism. The land-grab phase rewards the platforms; the reckoning phase, where you demand standards and proof, is where advertisers get real value.

Every hot channel runs the same cycle: land-grab, then reckoning.
