The global out of home (OOH) advertising market is witnessing steady growth as brands increasingly use outdoor advertising to reach consumers in high-traffic public locations.
According to Fortune Business Insights, the global out of home advertising market size was valued at USD 23.27 billion in 2025 and is projected to grow from USD 25.8 billion in 2026 to USD 58.8 billion by 2034, exhibiting a CAGR of 10.85% during the forecast period.
North America dominated the out of home advertising market in 2025, accounting for a 30% revenue share. The region's established advertising ecosystem, extensive urban infrastructure, and increasing adoption of digital outdoor advertising have supported its leading position.
Out of home advertising refers to advertising displayed in public spaces where consumers can view promotional messages while traveling, shopping, commuting, or participating in daily activities. Common formats include billboards, transit advertising, street furniture, digital displays, airport advertising, and advertisements placed in shopping centers.
The integration of digital technologies has transformed traditional OOH advertising by allowing advertisers to display dynamic and targeted content based on location, audience characteristics, time, and other factors.
The increasing urban population and expansion of cities are important factors supporting the growth of the OOH advertising market. High-traffic areas such as transportation hubs, highways, commercial districts, and shopping centers provide advertisers with opportunities to reach large audiences.
The rapid adoption of digital out of home (DOOH) advertising is another major growth driver. Digital displays enable advertisers to update content quickly, run multiple campaigns on a single screen, and use data-driven targeting capabilities.
Advancements in programmatic advertising are also transforming the industry. Programmatic DOOH allows advertisers to automate the buying and placement of outdoor advertising inventory, improving campaign flexibility and efficiency.
North America held the largest share of the global out of home advertising market in 2025, accounting for 30% of revenue. The region benefits from a mature advertising industry, high urbanization, and widespread deployment of digital displays.
The U.S. is a major contributor to regional growth due to its extensive network of billboards, transit advertising systems, digital signage, and large-scale outdoor media networks. Advertisers are increasingly combining OOH campaigns with mobile, social media, and other digital marketing channels to create integrated campaigns.
