TV Publishers Unite Under OpenAP to Standardize Streaming and Linear Ad Outcomes
Measuring the actual impact of a TV ad has long been a fragmented nightmare for advertisers. While digital ads offer precise conversion tracking, the bridge between a viewer seeing a commercial on a linear channel and then making a purchase—or streaming a show and taking an action—has remained murky. That’s about to change.
A powerhouse coalition of major TV publishers is partnering with OpenAP to launch a shared infrastructure designed to link first-party outcome data with campaign exposure. By creating a single integration point, the industry is moving toward a standardized way to measure “business outcomes” across both linear TV and streaming platforms.
- Unified Infrastructure: A group of leading media companies is using OpenAP to standardize how advertiser conversion data connects to publisher exposure.
- The Tech: The initiative centers on a cross-publisher conversion API for TV.
- Broad Support: Partners include NBCUniversal, Paramount, Fox, Warner Bros. Discovery and several other major media groups.
- Future Outlook: The rollout begins with collaborative pilots, with plans to introduce automated, agentic interactions for spend optimization.
Closing the Gap Between Exposure and Action
For years, the “streaming wars” haven’t just been about content; they’ve been about data. Advertisers have faced increasing pressure to prove that their spend actually drives sales, but doing so across multiple different networks and streaming apps usually requires dozens of separate integrations.
The new OpenAP initiative solves this by introducing a cross-publisher conversion API. Instead of every advertiser building a custom connection to every network, this API standardizes the signals. This means a “conversion”—whether it’s a website sign-up, a product purchase, or an app download—can be linked back to the ad exposure consistently, regardless of whether the viewer was watching a traditional cable broadcast or a streaming service.
Who is Involved?
The scale of this collaboration is significant. The partners joining OpenAP in this effort include:
- A+E Global Media
- AMC Global Media
- Fox
- Hallmark Media
- NBCUniversal
- Paramount
- Scripps Networks
- TelevisaUnivision
- Warner Bros. Discovery
Why This Matters for the Ad Market
This shift isn’t just a technical upgrade; it’s a strategic move to make premium TV more competitive against the “walled gardens” of social media and search giants. By making premium video easier to connect and measure, these publishers are removing the friction that often leads buyers to shift budgets elsewhere.
Ryan Gould, chairman of OpenAP’s board and president of U.S. Advertising sales, go to market at Warner Bros. Discovery, notes that advertisers are under growing pressure to prove performance while dealing with increasing complexity. He asserts that this cross-publisher initiative simplifies that challenge, making it easier to invest in strategic audiences across data-driven video.
What’s Next: Pilots and AI Integration
The industry won’t flip a switch overnight. The rollout is following a phased approach:
- Collaborative Pilots: The first phase involves select advertisers, agencies, and attribution providers to test the infrastructure.
- Initial Results: The industry expects to see the first set of data and results from these pilots over the next year.
- Advanced Workflows: OpenAP plans to debut new cross-publisher campaign workflows.
- Agentic Automation: Looking further ahead, the platform will add support for automated, agentic interactions. These AI-driven tools will help buyers allocate and optimize their spend across different platforms in real-time.
Frequently Asked Questions
What is a “business outcome” in TV advertising?
A business outcome is a specific, measurable action a consumer takes after seeing an ad. Examples include purchasing a product, signing up for a newsletter, or downloading an app. Standardizing these outcomes allows advertisers to see exactly which ads are driving revenue.
How does the conversion API differ from traditional measurement?
Traditional measurement often relies on estimated reach or third-party panels. A conversion API uses first-party data to create a direct, standardized link between the ad exposure and the actual customer action, providing a more accurate picture of ROI.
Will this affect how viewers experience TV?
No. This infrastructure operates on the backend between publishers, and advertisers. Viewers won’t see a difference in their interface, but advertisers will have a much clearer understanding of which content is effectively reaching their target audience.
The Bottom Line
The unification of these media giants under the OpenAP umbrella signals a turning point for TV advertising. By prioritizing interoperability over isolated data silos, the industry is finally building a measurement language that matches the complexity of the modern viewing experience. As we move toward automated spend optimization and agentic AI, the ability to prove performance in real-time will be the ultimate competitive advantage for premium video.
