The IAB Tech Lab, a global authority on digital advertising technical standards, has unveiled its Live Event Ad Playbook, designed to support and simplify ad monetization within live streaming events. Central to this initiative is the introduction of the Concurrent Streams API specification, developed through close collaboration with industry leaders Amazon, NBCUniversal, FreeWheel, and Index Exchange. This new protocol addresses the technical complexities involved in delivering seamless ads during live streams, particularly at moments of high viewership concurrency, such as major sports events, breaking news, or cultural moments.
Anthony Katsur, CEO of IAB Tech Lab, highlighted the growing dominance of streaming as the primary form of television consumption across the U.S. and globally. He noted the special challenges live streaming poses for inserting ads without disrupting the viewer experience, which the Concurrent Streams API aims to resolve. By providing real-time data on how many viewers are concurrently watching a stream, this API enables publishers and their server-side ad insertion (SSAI) partners to communicate live audience metrics more efficiently to advertising systems. This capability allows for faster, more precise ad decision-making, helping advertisers respond to traffic spikes and optimize campaigns during critical live moments.

Streaming services are expected to allocate over $11 billion toward acquiring sports rights this year alone, with major events like Super Bowl LX and the 2024 Paris Olympic Games driving enormous audiences. Given this rapid expansion, the Live Event Ad Serving Working Group comprising Amazon, NBCUniversal, FreeWheel, and Index Exchange formed to develop and share best practices, ensuring a transparent and scalable live streaming ad ecosystem.
FreeWheel’s General Manager, Mark McKee, emphasized the surging demand for live sports advertising, while Amazon’s DSP Director Neal Richter pointed to the necessity for flexible technical infrastructure that can adapt in real time to live event dynamics. NBCUniversal’s Chief Product Officer Ryan McConville underscored their deep experience in live streaming, reinforcing how these standards will benefit the broader industry. Index Exchange’s Lead Product Manager Catherine Cho described the high concurrency and unpredictability of live streams as both a challenge and opportunity, stating that the new standards aim to bring order to live programmatic advertising, making every impression actionable and valuable.

Looking ahead, the IAB Tech Lab is also developing an API to forecast viewership for upcoming live events over a rolling two to three-week period, enabling publishers and advertisers to better prepare for audience surges and fine-tune their strategies accordingly.
Together, these advancements offer the entire media supply chain a clear and standardized framework to deliver premium, reliable, and scalable ad experiences during live streamed events, supporting the continued growth and monetization of this rapidly evolving format.
