Viant-TVision Deal Fuels Call for Unified CTV Measurement
An ADWEEK House Possible panel co-hosted with Viant explored measurement, transparency and buying practices in Connected TV (CTV). Viant’s Chris Vanderhook said marketers want a unified, independent CTV measurement system and noted Viant recently acquired TVision, a company that uses cameras and eye-tracking to measure in-room audience counts and attention. Panelists including TVision CEO Yan Liu, agency and brand leaders from Spark Foundry, Marriott International, Molson Coors and Chobani discussed inventory transparency, the need for clearer supply data in programmatic buys and the continuing importance of creative to capture distracted viewers. The discussion highlighted app- and show-level placement opacity and urged both buyers and publishers to improve supply transparency to scale CTV effectively.
Viant’s acquisition of TVision and the industry discussion push momentum toward more transparent, independent CTV measurement—important for programmatic buying, viewability/attention measurement and supply transparency but not a platform-level policy shift.

CTV Consolidation Hits a Measurement Crossroads
Alex Yip, Director of Product Strategy at AppsFlyer, argues that consolidation across the Connected TV (CTV) ecosystem is driven by companies seeking control of four capabilities — the screen, the pipes, the checkout and measurement — but that measurement behaves differently. While screens, supply/pipes and checkout data gain value from ownership, measurement gains value from neutrality, interoperability and cross-platform visibility. Recent M&A activity (e.g., Fox/Roku, Walmart/Vizio/Vibe, Mediaocean/Innovid, DoubleVerify/Rockerbox, iSpot/605) shows companies assembling parts of the CTV stack, but measurement largely consolidates within its own layer even as platforms try to internalize it. The tension between closed-loop platform measurement and advertisers’ demand for independent, omnichannel measurement is the central unresolved issue in this consolidation cycle.
Broadcasters Tackle CTV Measurement and Transparency
As advertisers move billions into Connected TV (CTV), industry leaders warn the channel still suffers the transparency, measurement and quality issues that plagued early programmatic buying. Daniel Best, SVP at AI-powered creative effectiveness platform DAIVID, argues that CTV will only scale if buying and measurement become simpler and more transparent. Panel-based TV measurement is described as too slow and costly for modern, high-volume creative testing, prompting a shift toward outcomes-based measurement despite persistent signal gaps. Generative AI is lowering creative production costs and enabling large-scale testing, but Best cautions it’s not a substitute for strong creative ideas or quality control. Without improved accountability and fraud mitigation, the industry risks repeating programmatic-era mistakes that could undermine CTV’s growth.
CTV Measurement: From Impressions to Outcomes (Marketecture Live)
Jenny Wall of VideoAmp and host Ari Paparo discuss the evolution of connected TV measurement beyond traditional impressions and demos. The conversation covers outcomes-based attribution, advanced audiences, and the use of clean rooms, emphasizing the need for multiple currencies across linear, streaming, and walled gardens. They provide practical examples supporting audience-first buying, call for independent measurement, and caution against sticking to legacy metrics. Takeaways include that TV can deliver measurable business outcomes, advanced audiences reduce waste and can lift sales, cross-channel measurement is essential, third-party validation matters due to platform bias, and current dual currencies plus clean room matching, while painful, enable price flexibility and innovation. Real-time optimization in TV is approaching, challenging marketers to move beyond delivery metrics.
