The OOH advertising industry has reached a notable milestone with its market size hitting $9.46 billion, underscoring its resilience and adaptability amid the ongoing digital transformation. This growth is largely propelled by a surge in digital and programmatic advertising investments, with the UK standing out due to an anticipated 41% increase in pDOOH spending.
