What is OOH in Marketing? Defining the Landscape
OOH in marketing refers to any advertisement that reaches consumers when they are outside their homes.

Billboards and Static Outdoor Signs
Billboards remain the quintessential OOH asset. Their high impact arises from large scale, bold typography and estrategically chosen sightlines.
