MIAMI — In an industry that still occasionally treats gross rating points like sacred scripture, David Porter, head of advertising research, data and insights at Warner Bros. Discovery, arrived with this suggestion: maybe it’s time to upgrade the math.
Speaking with Beet.TV contributor David Kaplan at the POSSIBLE conference, Porter laid out a vision for advertising that involves fewer legacy habits and more, well, actual results. It is a conversation that touches everything from measurement currencies to AI to the radical notion that ads should drive business outcomes.
Currency market that actually has competition
Porter made it clear that the upcoming upfront season will not be a one-measurement show.
“As we approach the ’26, ’27 upfront season, we are ready to transact with three different currency providers,” he said, naming Comscore, VideoAmp and Nielsen like a man listing acceptable dinner options rather than sworn rivals.
That flexibility is not just a technical upgrade. It is a philosophical one.
“This optionality is critically important,” Porter said. “We need a competitive marketplace in the currency space.”
Translation: when measurement companies have to compete, they tend to try harder, which is a refreshing concept in any industry that has historically relied on inertia as a business model.
StreamX tries to solve fragmentation without therapy
If fragmentation has been advertising’s favorite complaint for the past decade, StreamX is Warner Bros. Discovery’s attempt to stop talking about it and actually do something.
“The appetite is very, very strong,” Porter said of advertiser interest in unified planning.
The pitch is simple. Instead of chasing audiences across linear, streaming and digital like a confused tourist, StreamX pulls them into a single plan.
“StreamX finds viewers across linear, streaming, digital, and brings them all together into a single unified plan,” Porter said.
And in case anyone needed proof that this is more than a tidy PowerPoint, Porter pointed to actual revenue. A campaign in the travel sector drove $10 million in incremental sales. Not impressions. Not engagement. Sales.
Clean rooms: less magic, more common sense
Clean rooms may not sound glamorous, but Porter insists they are quietly rewriting how advertisers think about data collaboration.
“That report certainly did change the conversation,” he said, referring to research showing a threefold increase in targetable IDs.
The reason is not mystical. It is logistical.
“It isn’t magical,” Porter said. “Just reducing the handoffs means better match rates, more targetable IDs.”
In other words, fewer middlemen, fewer data hops and fewer chances for your audience to disappear somewhere between platforms. A shockingly effective strategy.
AI is coming for your planning cycle
While premium video still dominates the present, Porter is already looking at what comes next. And it involves AI gently dismantling some of the industry’s favorite habits.
“Agentic AI is gonna start to chip away at the legacy industry operating norms,” he said.
Those norms include some familiar friends: gross rating points, age and gender demos, quarterly planning cycles.
Instead of optimizing for those proxies, Porter suggests the industry may finally focus on what advertising was supposed to do all along.
“We’re gonna get to the heart of really what advertising is meant to do, which is drive business performance,” he said.
The upfront, but with fewer illusions
Taken together, Porter’s comments paint a picture of an upfront market that looks less like a ritual and more like a functioning marketplace. Multiple currencies, unified planning, better data collaboration and AI-driven execution all point in the same direction.
For media buyers, this may require letting go of a few comforting metrics. For sellers, it means proving outcomes instead of promising reach.
For everyone else, it means accepting that the future of advertising may be less about what can be measured easily and more about what actually works.
And if that sounds obvious, well, that may be the most radical shift of all.
