OAAA's New Taxonomy to Unlock Programmatic DOOH's Full Potential

WASHINGTON, DC – February 10, 2026 – The Out of Home Advertising Association of America (OAAA) today announced the release of an updated OpenOOH venue taxonomy, a move designed to bring much-needed standardization and transparency to the rapidly growing digital out of home (DOOH) advertising landscape. The new framework aims to create a consistent, precise language for classifying DOOH inventory, directly addressing market demand for clearer standards to facilitate large-scale programmatic buying and selling.

As DOOH carves out a more significant role in complex, multi-channel advertising strategies, this enhanced taxonomy is built to integrate seamlessly with the planning, buying, and measurement tools used across the digital media ecosystem.

“With OOH becoming ever more deeply integrated into cross-channel media planning, a shared, precise inventory language is essential,” said Patrick Dolan, Chief Operating Officer of OAAA, in the announcement. “Clear, consistent standards are a growth engine for the industry—reducing friction, increasing confidence for buyers, and making OOH easier to plan, transact, and measure at scale.”

Addressing Friction in a Booming Market

The update arrives at a critical juncture for the OOH industry. The global programmatic DOOH market, valued at over $900 million in 2023, is on a steep growth trajectory, with some forecasts projecting it will exceed $6 billion by 2030. However, this rapid expansion has exposed significant growing pains, particularly the lack of a standardized system for classifying the diverse and proliferating array of digital screens.

Previously, the industry relied on a taxonomy that often grouped distinct venue types into broad, "historically bundled formats." A screen in a high-end luxury mall might be categorized similarly to one in a discount outlet center, and a display at a cinema entrance could be indistinguishable from one inside a sports arena concourse. This lack of granularity created significant friction for media buyers, who struggled to execute precise, context-aware campaigns. The ambiguity hindered their ability to confidently invest at scale, as it was difficult to ensure their ads were reaching the intended audience in the most relevant environment.

This inconsistency also created challenges for measurement and comparability. Without a shared set of definitions, comparing the performance of DOOH campaigns across different media owners and platforms was difficult, as was benchmarking DOOH against other digital channels like connected TV (CTV) or mobile. The old system acted as a bottleneck, limiting the full potential of programmatic automation and data-driven targeting that have revolutionized other advertising sectors.

From Bundled to Granular: A Closer Look at the Changes

The new OpenOOH taxonomy directly confronts these challenges by introducing a far more detailed and logical classification system. The framework deconstructs the old bundled categories, providing clear distinctions and introducing more granular classifications for the fastest-growing segments of the market.

Two areas receiving particular attention are retail media and entertainment venues. As retailers increasingly transform their physical stores into powerful media networks, the ability to differentiate between a screen at the checkout counter, one in a specific product aisle, or one at the store entrance becomes paramount for advertisers. The updated taxonomy provides this level of detail, allowing brands to target consumers at specific points in their shopping journey. Similarly, broad categories like "entertainment" are now broken down into more specific venue types, such as cinema lobbies, live music venues, or sports arenas, each with distinct audience behaviors and contextual opportunities.

This evolution provides advertisers with the tools for more sophisticated contextual targeting in the physical world. “The latest evolution of the OpenOOH taxonomy provides buyers with clear, granular and actionable information about the physical environment of each individual display,” noted Ari Buchalter, founder of Place Exchange and now Chief Strategy Officer at Broadsign. He added that this enables "contextual targeting in the physical world with confidence and precision, universally across all platforms.”

For sellers, the added clarity helps reduce planning confusion and ensures their valuable inventory is represented accurately to both programmatic and direct buyers, potentially unlocking higher value for premium placements.

Unlocking Omnichannel Potential and Accelerating Investment

Perhaps the most significant impact of the updated taxonomy will be its role in accelerating DOOH's integration into the broader omnichannel media ecosystem. By aligning OOH inventory language with the standards used in other digital channels, the framework makes it far easier for brands and agencies to plan, execute, and measure holistic campaigns that span the physical and digital worlds.

Marketers can now more seamlessly extend audience targeting strategies from online channels to DOOH and vice-versa, creating cohesive brand narratives. For instance, a consumer exposed to an ad on a screen in a specific type of retail environment can be retargeted on their mobile device, reinforcing the message and driving conversion. This interoperability is key to positioning DOOH not as a siloed channel, but as a core, measurable component of a unified marketing strategy.

Industry leaders expect this increased clarity and consistency to directly translate into greater investment. “When buyers clearly understand what they are purchasing across platforms, it reduces friction, increases confidence, and accelerates investment,” stated Premesh Purayil, Chief Technology Officer of OUTFRONT Media Inc. This confidence is crucial as programmatic DOOH ad spend is projected to surpass $1 billion in 2026. The ability to buy with precision removes a major barrier for digital-first media buyers who are accustomed to the granular data available in other programmatic channels.

A Cohesive Push for Industry-Wide Standards

The OAAA's taxonomy update does not exist in isolation. It represents a key piece of a larger, industry-wide movement to bring greater maturity and accountability to the OOH medium. This effort runs parallel to and complements the work of other major industry bodies.

The Media Rating Council (MRC), for example, recently finalized its comprehensive Out-of-Home Measurement Standards in late 2025 after a multi-phase development process. These standards establish a framework for quality audience measurement, covering metrics from gross impressions to "Likelihood-to-See," ensuring consistency with other audited media. Similarly, the Interactive Advertising Bureau (IAB) has been instrumental in developing guidelines for DOOH measurement and adapting its OpenRTB protocol to better accommodate the unique attributes of real-world screens.

Rather than competing, these initiatives are symbiotic. The OAAA's venue taxonomy provides the foundational "what" and "where" of DOOH inventory—the granular data about the physical context. This data then feeds into the programmatic buying frameworks defined by the IAB and can be measured against the audience and viewability standards set by the MRC. This collaborative approach, with the OAAA participating directly in the MRC's standards development, signals a unified push to build the infrastructure necessary for sustainable, long-term growth.

By establishing this shared language for venue types, the OAAA is laying the groundwork for the next era of DOOH advertising. This structured data is essential for enabling more advanced applications, from dynamic creative optimization based on real-time environmental triggers to AI-driven predictive analytics that can guide campaign planning. The new taxonomy is more than a simple update; it is a fundamental building block for a more transparent, scalable, and powerful out of home advertising future.
