What is OOH (out of home)?
OOH is the umbrella term for every advertising medium that meets people while they are out in the world. It includes billboards along highways, posters in subway stations, wraps on buses, ads on bus shelters and kiosks (street furniture), screens in airports, gyms, elevators and malls (place-based media), and the vast digital displays of places like Times Square. Digital out-of-home, or DOOH, is one of the fastest-growing parts of the category, because screens can change content by the hour and be bought programmatically.
OOH is one of the oldest advertising media (painted walls and posted bills go back centuries) and one of the few traditional channels that has held its ground in the digital era.
Why it matters
Why OOH matters
OOH cannot be skipped, blocked or scrolled past. It reaches people at scale, in the physical places where they live, commute and shop, often close to the point of purchase. It has a public quality that digital lacks: everyone sees the same billboard, which gives a brand a sense of presence and confidence that a targeted feed ad cannot. And it travels: striking OOH gets photographed and shared, so a single site can earn far more reach online than it delivers on the street.
For brands built on digital channels, OOH also sends a different kind of signal. Being on the street tells people the brand is real and here to stay.
In practice
How OOH works in practice
- 01
Media owners sell OOH by site, by package or by audience. A planner chooses formats and locations based on where the target audience moves (commuter routes, neighborhoods, venues, airports) and buys either fixed sites for a period or, in digital OOH, slots or impressions on networks of screens, often with time-of-day targeting. Audience measurement uses traffic and mobility data to estimate how many people pass each site.

The creative is then made for each format: static artwork sized and printed for posters and billboards, motion files built to exact specifications for digital screens, sometimes with live data feeds or location-specific messages. Proofs are checked against each media owner's requirements, the work is installed or uploaded, and the live sites are photographed for reporting and for social.

We made content for the Red Bull Kumite screens in Times Square, one of the most demanding OOH environments anywhere. Screens that size, seen from that distance by crowds that are moving, teach you to cut a film down to its strongest frames and let scale do the rest.
Watch out
What people get wrong about OOH
Treating it as a print ad on a bigger surface. OOH is seen for a few seconds, at a distance, often in motion, and creative that works in a magazine falls apart on a highway: one image, a handful of words and a brand visible at a glance is the discipline. The other mistake is assuming it cannot be measured. Mobility data, brand lift studies, search uplift in exposed areas and digital OOH attribution now make OOH far more accountable than its reputation suggests.
