IAB expands measurement for four CTV ad formats
IAB expands CTV impression measurement to four emerging ad formats. Buyers need to check SDK adoption and viewability definitions.
IAB Tech Lab has expanded its Open Measurement SDK to help the connected-TV advertising market measure four newer ad formats: pause, menu, screensaver and overlay placements. Its November 10 announcement targets a problem that standard video advertising assumptions cannot solve. An ad can appear on a streaming device without occupying the full screen, and the details of that placement matter when buyers assess viewability.
The IAB Tech Lab announcement extends common impression-measurement infrastructure to these formats. It does not claim that every streaming service has adopted the implementation, or that new measurement alone proves campaigns drive more sales. The practical change is a clearer technical basis for independent verification when participating apps and measurement providers integrate it.

Key Takeaways
- IAB Tech Lab has extended Open Measurement SDK support to pause, menu, screensaver and overlay ads on connected TV.
- The new capability concerns the measurement of existing ad formats, rather than the introduction of those formats for the first time.
- Buyers must verify actual publisher and measurement-provider implementation before treating the standard as coverage for a campaign.
What the new CTV measurement support covers
The expanded support addresses four distinct ad experiences. Pause ads show when viewers stop playback; menu or homescreen ads appear as people browse a streaming interface; screensaver units appear during idle states; and overlays can occupy only part of the display while content remains visible. These placements do not behave identically to a full-screen video commercial.
IAB Tech Lab's wider CTV Ad Portfolio had already established definitions and trading guidance for emerging television formats. The December 2025 portfolio announcement covered six formats. The November 2026 news is specifically about adding Open Measurement support for four of them, not about launching four previously unseen ad products.
That distinction matters to buyers. Standard format names help trading platforms identify what a seller is offering. Measurement support helps buyers and verification providers determine what happened when the impression was rendered. Those are related parts of the CTV supply chain, but neither automatically guarantees the other.
Why pause and overlay impressions need different checks
Traditional television commercials typically occupy the full viewing area during a break. A menu tile, pause-screen placement or overlay may use less screen space and may appear for different lengths of time. Treating each CTV impression as necessarily viewable would therefore hide material differences between placements.
In its independent coverage, MarTech highlights the same measurement challenge: these newer ad surfaces do not all behave like conventional video. A smaller overlay may remain visible while programming continues, while a pause ad may appear only during a viewer-initiated interruption. The event that triggers the unit and how it is presented both affect how marketers should interpret exposure.
For measurement, impression delivery and viewability must remain separate concepts. A served ad is a delivery event. The portion on screen, its duration and whether it can be independently verified require appropriate signals. Even a correctly measured viewable impression does not establish that a person looked at the creative, remembered the brand or made a purchase.
Advertisers should also resist combining incompatible formats in one reporting line without checking the definitions behind each metric. When a screen is idle, for example, an impression may be technically displayed while actual viewer presence remains unknown. An overlay beside ongoing content creates another exposure situation. Better verification narrows those ambiguities but does not eliminate the need for interpretation.
What publishers and verification partners must implement
The Open Measurement SDK supplies common code and interfaces that apps and verification vendors can use for measurement data. The official OM SDK documentation explains that integrations can provide signals about placement, time in view and device authenticity, while third-party measurement partners use those signals for verification. The standard is designed to reduce reliance on separate proprietary measurement integrations.
The technical path differs by device and app environment. IAB Tech Lab documents native app SDKs for Android TV and tvOS alongside a web-video approach for environments including Samsung and LG devices. Actual support depends on the integration choices made by streaming apps, ad technology providers and verification partners. A standards announcement is not a universal rollout notice from every publisher.
For sellers, consistent measurement could make nontraditional inventory easier to explain and compare. For agencies, common signals offer the prospect of applying more consistent buying rules across supply partners. These are operational opportunities rather than demonstrated campaign outcomes; the industry still has to implement, test and support the relevant format-specific capabilities.
Buyers should request documentation for the precise format and device combinations in their media plans. An app may support standard measurement for video commercials yet not have implemented the newly added menu or screensaver events. Asking for a provider name or a generic SDK label is not enough to establish coverage.
What advertisers should test before shifting budgets
A sensible first step is an inventory audit. Ask each CTV partner which of the four newly supported formats it sells, on which devices, and whether the relevant SDK integration is live. Ask the independent measurement provider whether it can receive, distinguish and report those exact signals. Document unsupported environments instead of presenting them as zero-viewability inventory.
Next, compare placements using metrics that genuinely make sense for each experience. Screen coverage and time in view may be directly relevant for overlays and menu units. Frequency, completion and downstream response can be useful when defined consistently, but a menu placement should not inherit conventional video-completion expectations merely because both are sold on a television screen.
Finally, test commercial impact separately from technical exposure. Marketers can compare formats with matched audiences, budgets and campaign windows where the buying platform permits it. Brand-lift, incremental reach or conversion experiments may provide different answers from impression measurement. The new standard helps establish what was displayed; marketers still need evidence of what the display achieved.
IAB Tech Lab's update gives a growing group of CTV placements a more consistent technical measurement foundation. The near-term advantage for advertisers is better questions to ask of streaming sellers and verification vendors. The broader commercial promise depends on adoption, coverage and useful reporting rather than the announcement alone.
