IAB launches RMT framework to unify fragmented digital video definitions

The RMT framework addresses a critical friction point where inconsistent definitions of 'CTV' or 'online video' lead to misaligned media planning and uneven measurement. By establishing a shared technical language, the IAB aims to reduce waste in the $81.9 billion digital video market and prepare the infrastructure for automated, AI-led transactions. For the broader ecosystem, this is a prerequisite for moving beyond legacy broad-reach metrics toward the precise, outcome-based reporting that advertisers now demand. Success hinges on widespread adoption by major platforms; watch for updates to the OpenRTB and AdCOM specifications later this year to see how these definitions are codified into actual trading protocols.

The RMT framework arrives as digital video advertising enters a period of maturity and technical transition. Per IAB reporting from May 2026, total digital video spend is projected to reach $81.9 billion this year, accounting for 61% of the total TV and video market. This growth is increasingly driven by the shift of premium sports rights to streaming platforms, including the NBA on Amazon and NFL on Netflix, which have moved high-value linear inventory into programmatic environments. Despite this scale, fragmentation remains a significant barrier, with a January 2026 analysis by Insider Intelligence noting that advertisers still struggle to manage frequency and supply quality across a mix of AVOD, FAST, and vMVPD services.

Technical interoperability has become more urgent as the industry moves toward 'agentic' advertising. Per IAB Tech Lab in March 2026, the organization is prioritizing open-source Agentic Advertising Management Protocols (AAMP) to support AI agents that automate planning and execution. Without standardized definitions like those found in the RMT, these AI models cannot accurately compare inventory across different delivery mechanisms. Parallel efforts in early 2026, such as the second public comment period for the CTV Ad Portfolio guidelines, indicate a broader push to standardize innovative formats like pause and shoppable ads.

Measurement transparency also remains a focus for major spenders. According to a February 2026 report from DoubleVerify, CTV advertisers are increasingly demanding sophisticated fraud detection as nearly 20% of impressions on some platforms have been linked to low-value or fraudulent content. By tying operational attributes directly to the consumer viewing experience, the RMT framework seeks to bridge the gap between how viewers perceive content and how technical systems validate and bill for that exposure.
