CTV Graduates: Definitions Still Matter
IAB Tech Lab argues that the Advanced TV ecosystem has matured: the OTT vs. CTV distinction now drives technical implementations, standards and commercial practice rather than purely semantic debate. Definitions influence signaling and buying logic in OpenRTB 2.6, creative and SSAI consistency in VAST 4.3, and structured transactions via AdCOM. IAB Tech Lab highlights the CTV Ad Portfolio and standardized use of OpenRTB/AdCOM, Native API and VAST to describe CTV ad units, while measurement standards (VAST 4.3, SIMID, OM SDK for CTV, ACIF Universal Ad ID) and server-to-server conversion APIs (ECAPI) aim to make measurement consistent and trusted. Live streaming and high-concurrency events remain a technical challenge (LEAP, podded bidding). The piece concludes the industry is aligned around CTV as the primary commercial focus and is now operating to scale via interoperability and standardized systems. Published 2026-05-12.
Standards and consistent definitions across OpenRTB, VAST, AdCOM and measurement specs materially improve programmatic CTV interoperability, measurement and scale—important for ad buyers, sellers and verification but not a single platform policy shift.

CTV Matures: Industry Unites for Standards and Innovation
IAB Tech Lab recapped the I Want My CTV 2025 event, emphasizing that Connected TV (CTV) has matured from experiment to a cooperative industry marketplace. Brad Pipkin, newly appointed Director of Product Management for Advanced TV at IAB Tech Lab, highlighted standards and collaboration as central themes. Panels and keynotes promoted standardization efforts — including OpenRTB, Deals API, OM SDK (v1.6 device attestation), Forecasting and Concurrent Streams APIs, and a public comment period for the CTV Ad Portfolio (opened December 11). Sessions covered new ad formats, measurement and verification challenges, edge delivery for live events, and the commercial potential of novel devices and formats (for example, Telly). Speakers urged cross-industry participation in working groups to drive interoperability, measurement integrity, and scalable programmatic monetization for future live and on-demand CTV inventory.
CTV Ad Ops Matures into Repeatable Operations
IAB Tech Lab reported at its 2026 Ad Ops Workshop for Advanced TV that Connected TV (CTV) has reached scale (projected at $29.3B in U.S. spend for 2026) and needs more mature, repeatable operating infrastructure. The workshop highlighted finalized CTV Ad Portfolio guidance (six ad formats), two delivery paths using OpenRTB/VAST and the Native API, tools and APIs for earlier creative approval and validation (Ad Management API, Next‑Gen VAST Tester), and standards for event reporting and creative identity (ECAPI, ACIF, UniversalAdID). Attendee polls showed meaningful early adoption intentions but also identified organizational and data-access barriers to measurement and identity. The Tech Lab emphasized that publishing standards is only the start — real value requires broad implementation, governance, and partner participation.
Global Brands Ditch Labour-Based Agency Fees, WFA Finds
A new report from the World Federation of Advertisers (WFA) and Agency Mania Solutions, titled 'How Brands Define, Scope and Reward Agency Work', reveals a significant shift in agency compensation models. Based on responses from 69 multinational companies with a combined marketing spend of $147 billion, the report finds that labour-based payment models, which were dominant in 2011, now represent the main compensation model for only 19% of global brands. Meanwhile, fixed-fee/output models have risen to 33%, and 'Labour + Performance' models to 21%. Performance-based fees show the strongest momentum, with 63% of multinationals expecting to increase their use, driven by AI, which is compressing labour hours. However, only 20% have evolved their commercial models in response to AI, though 61% intend to. The report also notes a shift in focus towards factors like briefing quality and trust over financial incentives.
