IAB Tech Lab Proposes Programmatic Rules
IAB Tech Lab has released for public comment its Programmatic Standard Practices v1, a set of shared business rules, norms, and principles for using existing programmatic advertising standards. The proposal aims to reduce transaction friction, improve transparency, and establish consistent governance across the programmatic ecosystem. It is the first deliverable from the Programmatic Governance Council, which addresses business and governance issues in programmatic advertising. The practices focus on how companies should use existing technical standards, not introducing new ones. Public comment is open until October 16. This initiative seeks to clarify expectations between buyers and sellers and strengthen trust among the numerous intermediaries in the ecosystem.
A governance initiative from IAB Tech Lab that could shape programmatic transaction practices and reduce industry friction.

IAB Tech Lab Introduces AAMP 3.0 to Standardize the RFP-to-Buy Process for Agentic Advertising
IAB Tech Lab has announced AAMP 3.0, introducing OpenProposal, a specification to standardize the RFP-to-buy process for agentic advertising. OpenProposal enables AI agents to discover, compare, and negotiate media proposals by defining machine-readable proposal data across eleven headers in categories like Merchandising, Optimization, Commitment, and Reconciliation. It is transaction-type agnostic (supporting Direct IOs, Programmatic Guaranteed, etc.) and channel agnostic (covering display, CTV, audio, OOH, linear TV). Additionally, IAB released the Measurement Services Addendum v1.0, a contractual framework for measurement, verification, attribution, and analytics services. Both initiatives are open for public comment until October 22, 2026, and aim to improve efficiency and standardization in programmatic media buying and measurement.
IAB Tech Lab Publishes Programmatic Auction Definitions
The IAB Tech Lab has released the final Programmatic Auction Definitions document, developed with its Programmatic Supply Chain subgroup to provide a common vocabulary for how digital auctions operate in OpenRTB environments. The work supplements the Media Rating Council’s Digital Advertising Auction Transparency Standards, which were produced by the MRC’s Auction Standards Working Group to promote disclosure and standardization of auction rules and scoring. The definitions followed a public comment period in January–February 2026 and are available on GitHub. The announcement cites prior 2025 collaboration between the Media Rating Council, Omnicom Media Group and industry bodies (ANA, WFA, 4A’s, and IAB Tech Lab) to improve transparency in digital advertising auctions.
IAB Calls for Programmatic Supply-Chain Transparency
An IAB blog post by Angelina Eng (May 18, 2026) argues the programmatic advertising supply chain lacks clear visibility into fees and revenue flows, leaving a large portion of advertiser spend not reaching publishers. The piece cites industry research (ANA, ISBA, Jounce Media) on low working-media efficiency and describes contractual and technical barriers to disclosure. It highlights ongoing industry efforts — IAB Tech Lab’s Programmatic Governance Council and IAB’s Project Eidos — to build standards, taxonomies and standardized terms and conditions. The author proposes five practical steps for near-term progress, including standardized fee reporting, impression-level cost reconciliation, explicit opt-in for paid services, publisher-side revenue breakdowns, and a common fee taxonomy.
