The Out of Home Advertising Association of America (OAAA) has introduced a revised taxonomy for the out-of-home (OOH) advertising sector. This update is designed to standardize industry terminology and definitions, with the potential to transform how ad buying, measurement, and reporting are conducted across the industry.

Who should care: DOOH network operators, digital signage program managers, ad-tech platform leaders, display technology decision-makers, and out-of-home advertising teams.

What happened?

The OAAA has unveiled a comprehensive update to its taxonomy, marking a significant step toward redefining the OOH advertising landscape. This revised taxonomy establishes standardized terms and definitions that aim to unify the language used throughout the industry. By doing so, it seeks to streamline the buying and selling processes for OOH advertising, reducing ambiguity and fostering consistency among all participants.

Among the key changes are new definitions and classifications that reflect the latest technological advancements and evolving market practices. This ensures that advertisers, media owners, technology providers, and other stakeholders operate with a shared understanding of critical concepts, which is essential for efficient collaboration and transaction execution.

Moreover, the updated taxonomy is poised to have a substantial impact on measurement and reporting standards. By providing a unified framework, it enhances the credibility of OOH advertising as a measurable medium, enabling more accurate and reliable data collection and analysis. This development is particularly important as the industry increasingly leverages data-driven insights to shape advertising strategies and investment decisions. Ultimately, the OAAA’s initiative is expected to bring greater transparency and operational efficiency to the marketplace, benefiting advertisers, media owners, and technology vendors alike.

Why now?

This update arrives at a pivotal moment as the OOH advertising industry experiences rapid transformation fueled by technological innovation and a growing emphasis on data analytics. Over the past 18 months, there has been mounting demand for standardized measurement and reporting practices that ensure accountability and transparency. The revised taxonomy directly addresses this need by aligning with broader industry trends toward greater standardization and clarity, providing a common language to support the sector’s evolving dynamics.
