VIOOH

VIOOH is a global digital out-of-home (DOOH) advertising technology company that operates a programmatic marketplace for buying and selling outdoor advertising inventory. Founded as a joint venture by JCDecaux, Clear Channel, and Stroer, VIOOH has established itself as a leading platform enabling automated, data-driven transactions for digital billboards and other out-of-home media assets. The company provides a supply-side platform (SSP) that connects premium DOOH inventory with demand-side platforms (DSPs) and agencies, facilitating programmatic buying at scale. VIOOH's platform enables advertisers to plan, buy, and measure DOOH campaigns programmatically across multiple markets and media owners. The company has expanded its reach globally, integrating inventory from numerous DOOH media owners beyond its founding partners. By bringing programmatic capabilities to the traditionally manual OOH buying process, VIOOH has positioned itself as a critical infrastructure player in the digitization of outdoor advertising, offering real-time bidding, audience targeting, and campaign optimization capabilities that align DOOH with digital advertising standards.
