IAB and IAB Tech Lab Release Redefining Media Types Standard for Digital Video, a joint framework that aims to bring uniform definitions to the fragmented world of online video advertising.
The Interactive Advertising Bureau (IAB) announced on July 9 that its new Redefining Media Types (RMT) Standard is now open for public comment through August 8. Developed with IAB Tech Lab, the specification delivers a two‑layer taxonomy that classifies video inventory by viewer experience and by granular impression‑level attributes.
Why a New Standard Matters
The video ad ecosystem has outgrown the legacy labels that were originally tied to broadcast technology. Brands, agencies, and publishers often speak past each other—one side may refer to “CTV,” while another uses “over‑the‑top” or “FAST,” leading to mismatched buying strategies and inconsistent measurement. The RMT framework tackles this mismatch by grouping environments into three macro buckets—Lean Back Viewing, Personal Screen Viewing, and Passive & Communal Viewing—based on how users engage with the screen, not on the underlying delivery tech.
A second, more technical layer adds binary signals such as sound state, skip‑ability, full‑screen mode, addressability, and measurability. These attributes can be embedded directly into OpenRTB bid requests, enabling real‑time, impression‑level decisions that align with the macro‑level planning language.
Industry Impact
For enterprise marketers, the standard promises a clearer roadmap from strategic media planning to execution. A unified language reduces the risk of overpaying for inventory that doesn’t match the intended consumer experience. At the same time, publishers gain a consistent way to package and price inventory, potentially unlocking higher yields from premium formats.
From a technology standpoint, the RMT Standard dovetails with IAB Tech Lab’s OpenRTB and AdCOM specifications, as well as the Measurement Center’s Project Eidos taxonomy. This alignment means that ad‑tech platforms—DSPs, SSPs, and DMPs—can adopt the taxonomy without building separate translation layers, accelerating industry‑wide adoption.
Comparative Landscape
Competing initiatives, such as Google’s Video Ad Formats and Amazon’s Sponsored Video, focus on product‑specific definitions that serve their own ecosystems. The RMT Standard, by contrast, is vendor‑agnostic and positioned as a cross‑industry reference. While Google’s Video Ad Formats excel in serving the YouTube ecosystem, they do not address the broader mix of FAST channels, retail video, and social video that the RMT taxonomy covers.
Enterprise Use Cases
- Strategic Planning: A global CMO can now map spend across Lean Back, Personal Screen, and Passive viewing buckets, ensuring budget aligns with brand safety and engagement goals.
- Programmatic Buying: DSPs can bid on “Full‑screen + Addressable” impressions, reducing wasted spend on non‑viewable or low‑impact inventory.
- Measurement & Attribution: By standardizing signals, analytics platforms can produce apples‑to‑apples performance reports across OTT, CTV, and social video.
Expert Voices
Jamie Finstein, IAB’s VP of Media Center, emphasized that the framework “gives buyers, sellers, publishers, and platforms a shared, future‑proof language.” Anthony Katsur, CEO of IAB Tech Lab, added that the partnership “connects these definitions to the technical standards and infrastructure needed for industry‑wide adoption.”
Statistical Context
- Gartner predicts global programmatic video spend will exceed $45 billion by 2025, a 23 % CAGR from 2022.
- Forrester reports that 71 % of marketers now consider video a top priority for audience acquisition, yet 58 % cite inconsistent inventory definitions as a major barrier.
Looking Ahead
The RMT Standard is slated to feed directly into Project Eidos, shaping the next generation of measurement taxonomy. As AI‑driven creative optimization and privacy‑first targeting become mainstream, a stable, shared vocabulary will be essential for scaling cross‑device campaigns without fragmenting data pipelines.
Conclusion
By delivering a unified, experience‑first classification system, the Redefining Media Types Standard could become the lingua franca of digital video advertising. If the public comment phase yields broad consensus, the framework may set the foundation for more transparent, efficient, and measurable video ecosystems—benefiting everything from Fortune 500 marketers to niche publishers.
Market Landscape
The video advertising market continues its rapid expansion across Connected TV, OTT, and social platforms. While ad spend is shifting away from traditional linear TV, the lack of consistent terminology has slowed cross‑platform optimization. The RMT Standard arrives at a moment when advertisers are demanding granular inventory insights to justify higher CPMs for premium environments. Its integration with OpenRTB positions it to be the de‑facto standard for programmatic video, potentially displacing fragmented proprietary schemas that currently dominate the space.
Top Insights
- The RMT taxonomy bridges strategic planning and real‑time bidding, reducing translation gaps between media teams and ad‑tech platforms.
- Vendor‑agnostic definitions enable cross‑platform measurement, a critical need as 62 % of marketers run campaigns across CTV, OTT, and social video.
- Alignment with OpenRTB and Project Eidos accelerates adoption, making the standard more than a whitepaper—it’s a functional component of the ad‑tech stack.
- Enterprise marketers can now allocate spend by viewer experience, improving ROI and brand safety in an increasingly fragmented video landscape.
- Early industry feedback suggests the framework could become a prerequisite for premium inventory access on major SSPs by 2027.
