DOOH extends a campaign into the physical world: the household that saw a streaming TV ad can meet the same message on a billboard along their commute. (Omnya does not sell DOOH; its six channels are Streaming TV, YouTube, Display, Audio, Meta and Search.)
Programmatic buying brought audience-based planning to out-of-home — screens are selected for the audiences that pass them, with flexible budgets instead of long-term billboard leases.
