Measurement
State of Play
Revised Nov 1, 2026The moment. The count changed what it counts. Comscore’s new Score Report ranks TV and streaming by share of ad-exposure time rather than viewing, and its first reading puts broadcast at 43.2%, cable at 34.5% and streaming at 22.3%. VideoWeek has NBCUniversal and Versant leading the August table at 17.5%, with a merged Paramount-WBD set to top it at 23.9%. iSpot’s Q3 report has streaming splitting ad revenue evenly with linear even though linear still delivers the vast majority of impressions, which is the same gap seen from the money side. Political money is the other pressure on the count: forecasters now project $12 billion for the 2025–26 midterm cycle, with local broadcast holding 50% of the $11.038 billion spent cycle-to-date against CTV’s 21%, and eMarketer has that spending crowding holiday marketers out of TV and CTV inventory.
The tension. Buyers want more precision from a surface that shows them less. Nielsen found 55% of marketers trust AI-generated recommendations only when a human verifies them, and says the share prioritizing measurement precision has doubled year over year. AdExchanger’s guest column argues B2B buying has moved into AI assistants, private messages and dark social that ad tech cannot observe. Extreme Reach’s John Batter says the industry still has no creative ID to tie ad variants to masters or production cost to outcome, and AI is multiplying the variants. The platforms are supplying the proof themselves: OpenAI’s Ads Manager now imports 30 days of aggregate Google Analytics 4 data so advertisers can run attribution comparisons inside it, and a six-month WPP Media study with Amazon Ads is the evidence offered that streaming moves sales. TVREV’s Sofie Sue Rutgeerts argues attention is a middle step, not the outcome. The sell side keeps answering the measurement question with its own numbers.
Who’s moving. Comscore, counting ad exposure instead of viewing. Comscore again, reporting Q3 results on November 3. iSpot and TVREV’s Jason Damata, on revenue parity at a fraction of the impressions. Extreme Reach’s John Batter, on the missing creative ID. OpenAI, wiring GA4 into its own ads manager. MediaPost’s Joe Mandese, on $12 billion and CTV’s 21%. eMarketer’s Marisa Jones, on political crowding out the holidays. Truthset and Aristotle, verifying identity on political CTV buys. Databricks, pitching prediction over impressions. Nielsen, with streaming at 58% of minutes for the top animated series. eMarketer’s Asa Hiken, on CTV conversion rates rising. Nielsen again, confirming a WNBA Finals Game 1 record of 1.76 million viewers.
What the desk is watching. Whether buyers start pricing on Comscore’s exposure share rather than viewing share, and whether the November 3 call puts revenue behind the new report.
