Interactive CTV Ads Move From Demos to Scale
Interactive connected-TV (CTV) ad formats — long showcased in industry demos — began reaching practical, programmatic scale in 2025. Pause ads emerged as the most-adopted interactive format, with vendors (Wunderkind, Kargo, Magnite, PubMatic, TripleLift) and publishers (Fubo, NBCUniversal planned for 2026) launching programmatically transactable pause ad products. The IAB Tech Lab published a CTV ad portfolio and guidance (Ad Format Hero initiative) and is moving toward detailed technical specs to standardize creative specs, metadata and signaling for interactive functions in VAST-supported environments. Case studies and surveys cited high viewer engagement during pauses and measurable campaign uplifts (e.g., QR-scan increases for Zales). Industry participants noted technical advances in measurement and called for common signaling (examples: video.plcmt, sellers.json for CTV) to enable interoperable programmatic execution of emerging CTV formats.
Interactive CTV formats have moved from demos to programmatic deployments and industry standardization (IAB Tech Lab guidance) is underway. This enables new interoperable ad inventory and measurement capabilities that can change CTV monetization dynamics, though it is not a systemic industry shift on the level of core platform policy changes.

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.
CTV Ad Formats Standardized: A New Era Begins
IAB Tech Lab's Ad Format Hero initiative standardized CTV ad formats after a year-long industry effort. More than 40 companies submitted well over 100 format examples; an Ad Format Hero Task Force grouped submissions, surveyed buyers and sellers, and narrowed the field from eight candidate formats to six final formats published as the CTV Ad Portfolio. Two candidate formats were consolidated: Immersive/Extensible Ads was treated as a feature (largely supported by SIMID) rather than a standalone format, and Ad Squeeze Back was considered an existing in-stream pod slot. The CTV Ad Portfolio and an updated CTV Programmatic Guide were published on December 11, 2025 and opened for public comment through January 31, 2026. Further work is planned to update OpenRTB, VAST, AdCOM, and SIMID signaling to enable full programmatic trading.
