18/02/2025 6:11 PM

The Out-of-Home (OOH) advertising sector continues to grow, reaching a record £1.4 billion in revenue in 2024, a 7.7% increase from the previous year. This surge was driven by a 10.2% rise in Digital Out-of-Home (DOOH) advertising, which now accounts for 66% of total OOH revenue. As the industry moves forward in 2025, advertisers must adapt to evolving trends, economic fluctuations, and emerging technologies to maximise their media investments.

Record Revenue and Digital Growth
The increasing reliance on DOOH demonstrates the sector’s shift toward more dynamic and targeted advertising solutions. Advertisers are leveraging digital capabilities to enhance audience engagement, providing more flexible and interactive campaigns.
