OAAA

The dominant trade association for the U.S. OOH advertising industry, representing the vast majority of OOH revenue and operators nationwide

The Out of Home Advertising Association of America (OAAA) is the primary trade organization for the out-of-home advertising industry in the United States. Founded in 1891, it represents over 800 member companies including billboard operators, transit advertisers, street furniture providers, and digital OOH (DOOH) vendors. OAAA provides advocacy, legislative support, research, and marketing resources to help its members grow and navigate the evolving OOH landscape. OAAA plays a central role in shaping industry standards, promoting OOH measurement methodologies, and educating advertisers and agencies about the effectiveness of out-of-home media. The organization publishes industry revenue data, conducts consumer research, and collaborates with bodies like the Traffic Audit Bureau (TAB) and Geopath to advance audience measurement. It also hosts the annual OAAA/Geopath OOH Media Conference, one of the industry's premier events. In the AdTech ecosystem, OAAA is significant as a convening force that bridges traditional OOH operators with emerging programmatic DOOH technology providers. As digital out-of-home advertising has grown rapidly, OAAA has expanded its focus to include programmatic buying, data-driven targeting, and integration with broader omnichannel advertising strategies, making it a key voice in modernizing the OOH sector.
