OOH: An Industry in Transition

While many traditional advertising channels struggle with declining reach or decreasing efficiency, Out-of-Home advertising (OOH) has shown clear growth momentum for several years. With 16 consecutive quarters of positive growth, OOH proves its relevance in today's media mix, not as a nostalgic relic, but as a stable channel in an evolving advertising landscape.

Current Nielsen data clearly demonstrates that this growth is no coincidence. The German advertising market shrank by 0.9 percent overall in 2025. In this environment, OOH grew by 9.9 percent, reaching an annual revenue of 3.56 billion euros, compared to 3.2 billion euros the previous year. Particularly noteworthy: In summer 2025, OOH crossed the 10 percent threshold of the total advertising market for the first time and has maintained double-digit market shares monthly ever since.

This growth should not be viewed in isolation. Rather, it reflects a larger trend: while digital channels are changing due to increasing fragmentation, ad-blocking, data privacy concerns, and AI fatigue, OOH remains largely unaffected. Physical presence in public spaces ensures visibility, independent of algorithms or user settings.

Media Usage and Reach: Why Out-of-Home Advertising Benefits

Consumer usage habits are continuously evolving. Linear television continues to lose reach, radio is increasingly being replaced by podcasts, and digital ad formats struggle with declining attention. At the same time, people are increasingly on the move again: in cities, traveling, at events. This is precisely where OOH unfolds its impact, with formats that are present where target audiences actually spend their time.

Additionally, trust in advertising formats is gaining importance. Studies show that OOH is perceived as particularly credible compared to digital channels. Advertising in public spaces is perceived as less intrusive, an advantage in an environment of increasing advertising fatigue.

Dynamic, Data-Driven, High-Growth

The Digital Out-of-Home (DOOH) segment is developing particularly dynamically, driving OOH's overall growth as an integral part of it. According to Nielsen, DOOH grew above average again in 2025. Gross advertising revenue increased by 26 percent to approximately 1.7 billion euros, representing a market share of 48 percent within Out-of-Home advertising.

DOOH: Sustained Growth Trajectory

What makes this growth particularly significant: it's not a one-time effect. DOOH already grew by 25 percent in 2023 and 19 percent in 2024. The growth trajectory has continued for years and is accelerating once again. The fourth quarter of 2025 particularly underscores this trend, with approximately 27 percent growth compared to the same period last year. Compared to December 2024, gross advertising revenue even increased by approximately 54 percent.

In the At-Retail-DOOH segment, the increase was even 92 percent compared to the previous year's month. According to IDOOH, a key driver was the Christmas season: advertisers specifically leveraged DOOH's flexibility and reach to motivate consumers to make short-term purchases.

The Strengths of Digital Out-of-Home Advertising

DOOH stands out with characteristics that are increasingly in demand today. Creative content can be adapted or exchanged on short notice. Geotargeting and programmatic advertising enable precise targeting. High frequency at urban hubs ensures rapid reach, while content appears in controlled, appropriate environments.

Conclusion

OOH is evolving from traditional poster surfaces to dynamic, data-driven communication spaces in the public realm. Especially in an increasingly complex advertising environment, OOH proves to be a robust channel that not only guarantees visibility but also trust and impact. Media agency forecasts for 2026 are clearly positive. For brands looking to future-proof their media strategy, it's worth taking a fresh look at the potential of Out-of-Home advertising, both traditional and digital.
