OOH (Out-of-Home) Advertising
OOH advertising is advertising that reaches people in public spaces outside their homes — billboards, transit ads, and out-of-home digital screens.
Definition
Out-of-Home advertising covers billboards, transit and airport ads, and digital out-of-home (DOOH) screens — media formats seen in the real world rather than on a personal device.
Why It Matters
OOH builds broad brand awareness and reach in a way that's hard to skip or block, and works well alongside digital retargeting.
Real-World Example
India's quick-commerce brands have used aggressive OOH campaigns — billboards and transit ads across metro cities — to build mass awareness alongside their app-based growth.
How It Connects
OOH sits within the broader media plan, often working alongside digital and programmatic buys for full-funnel reach.
