CTV Format Fragmentation Is Blocking Programmatic Scale for Pause and Interactive Ads
The Development
During the 2026 upfronts, Netflix and Warner Bros. Discovery joined Amazon and NBCUniversal in launching programmatic pause ads, signalling mainstream momentum for advanced CTV formats. But when IAB Tech Lab's Ad Format Hero initiative solicited submissions for standardisation candidates, it received more than 100 distinct formats — each with proprietary specs, unique asset requirements, and platform-specific rendering rules. The result is a market where enthusiasm consistently outpaces revenue: integrations get built for single publisher-vendor pairs, spend concentrates in small pockets, and eventually declines. OpenGlass TV, an SSP built specifically to translate publisher-level requirements across pause ads, home screen placements, squeezeback, L-bars, and side-by-sides, launched programmatic activation for these formats, connecting directly to DSPs to enable the same measurement infrastructure used for standard CTV inventory.
Our Take
Publishers are making a rational short-term choice: unique formats protect premium positioning and prevent their inventory from being commoditised. The problem is that their collective rationality produces an irrational market. Advertisers cannot build repeatable playbooks, agencies cannot staff efficiently against dozens of bespoke integrations, and spend stays concentrated with the largest direct IO relationships. The real unlock here is not standardisation of the format itself — that battle is lost — but standardisation of the workflow around it. A translation layer that absorbs publisher idiosyncrasy and presents a uniform buying surface to DSPs is worth considerably more than another point solution. Roku's Q1 data — 30 percent of ad revenue from non-media and entertainment advertisers — confirms the demand signal exists outside endemic categories. The bottleneck is operational, not commercial.
What Changed
Programmatic activation of non-standardised CTV formats — pause ads, home screen placements, squeezeback, L-bars — is now available through a translation layer that converts proprietary publisher specifications into DSP-compatible requests, enabling one-to-one audience targeting and standard measurement without requiring creative standardisation across publishers.
Marketing Impact
Media buying teams can now execute programmatic pause ad campaigns with one-to-one audience targeting and DSP-native measurement, without managing bespoke publisher integrations. CRM-driven retargeting of lapsed customers via pause ad inventory, previously only viable through direct IO, is operationally accessible for the first time.
Competitive Implication
Brands with existing programmatic infrastructure and first-party audience data gain immediate leverage — pause ad inventory becomes a CRM activation channel overnight. Agencies still routing advanced CTV formats through direct IO relationships face margin compression as the buying workflow commoditises, and publishers that refuse to connect to translation-layer SSPs risk exclusion from programmatic demand entirely.
Strategic Outlook
Expect IAB Tech Lab to focus standardisation efforts on workflow and delivery specs rather than creative formats, validating the translation-layer model. Additional SSPs will attempt to replicate OpenGlass's approach, compressing its first-mover window. Publishers will selectively connect where programmatic demand exceeds their direct IO revenue, not before.
The Exploit
Action Item
Media buying teams managing CTV investment above $5M annually should run a Q3 2026 pause ad test using first-party CRM segments through a DSP already connected to OpenGlass TV, specifically targeting lapsed purchasers with QR-enabled creative to generate attributable conversion data before the format attracts category-level pricing premiums.
