Outdoor Advertising Statistics

Digital out-of-home is pushing global OOH toward $49.6 billion by 2028, with DOOH already taking 33% of spend in 2022 and rotation capacity that can reshuffle up to 6 to 8 billboards an hour. The page connects that momentum to what regulators and buyers really constrain and reward, from US lighting and size limits to a 5.7% purchase intent lift reported by Kantar.

Outdoor advertising is moving fast enough to feel like a different medium now that the global OOH market is forecast to hit $49.6 billion by 2028. Even more telling, programmatic and digital formats are reshaping both what audiences see and how quickly brands can cycle messages, from the limits on rotating billboards to the regulatory guardrails that keep highway signs readable and safe.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
