The IAB Tech Lab, in partnership with Amazon, NBCUniversal, and other industry heavyweights, has released its "Live Event Ad Playbook," introducing new technical standards aimed at preventing ads from failing during high-traffic live streams. The core of the initiative is a new API designed to give ad systems a real-time headcount of viewers, cutting the risk of glitches during peak moments.
A high-stakes game: The move comes as streaming services pour an expected $11 billion into sports rights this year alone, and the industry is scrambling to build infrastructure that won’t collapse under the weight of massive audiences. IAB Tech Lab CEO Anthony Katsur notes that delivering a seamless stream is already hard, but "seamlessly inserting ads during those peak moments of concurrency is even harder."
The technical fix: The new "Concurrent Streams API" gives ad systems a real-time viewer count, allowing publishers to make faster decisions and avoid missed ad breaks when viewership spikes. According to Amazon DSP Director Neal Richter, the goal is to establish "a more reliable set of standards that benefits viewers, content creators, and brands."
Fighting on multiple fronts: The push to standardize live streaming is just one way the IAB Tech Lab is working to impose order on a chaotic digital media ecosystem. The organization recently gathered publishers to forge a united front against AI scrapers and earlier this year launched "Trusted Server," an initiative to help publishers reclaim control from restrictive web browsers.
The bottom line: As more high-value content moves to streaming, the lack of technical standards becomes a multi-billion-dollar problem. This playbook is an attempt to build guardrails for a valuable but fragile part of the digital ad market, ensuring the money flowing into live events actually reaches its target.

Also on our radar: While the industry sets new standards, the stakes for content quality remain high, with ad network Mediavine terminating publisher accounts over the use of AI-generated content. The fight over content control is also expanding beyond commercial publishers, as reports show AI bots are scraping data from public libraries and archives. All this unfolds as marketers signal plans to increase programmatic ad spending, pouring more money into the very ecosystem these initiatives are trying to stabilize.
