DOOH advertising is a modern take on old-school static billboards, powered by digital signage technology. After advertisers flocked to digital and away from DOOH early in the pandemic, the trend is now reversing with DOOH budgets bouncing back. Digital screens are dynamic—they can activate the right message to the right target audience at the right time. As the industry evolves from “one-to-many media” to “one-to-select media”, DOOH advertising is becoming a core part of advertisers’ multichannel strategy.
