For decades, broadcast radio has been the biggest blind spot in advertising — a $15 billion medium that reaches 9 out of 10 Americans but offers almost no targeting or measurement. iHeartMedia just fixed that. The question isn't whether advertisers will embrace AudioGraph. It's whether radio can finally claim the share of ad spend it's always deserved.

The numbers have always been absurd. Broadcast radio reaches more than 278 million Americans every month — 9 out of 10 people in the country. It accounts for 64 percent of all audio consumption. Yet for decades, it has operated like a medium frozen in time. Advertisers bought demographic buckets — age, gender, geography — and hoped for the best. They had no way to target specific audiences. No way to measure outcomes. No way to attribute a store visit to a spot they'd run on a morning show.

Digital audio, by contrast, offered precision. It offered targeting. It offered measurement. And it captured a disproportionate share of ad spend, despite reaching a fraction of radio's audience.

On Thursday, June 18, 2026, iHeartMedia — the No. 1 audio company in America — finally closed that gap. The company unveiled AudioGraph, a suite of advertising capabilities built by its Triton Digital subsidiary that, for the first time, brings digital-like targeting, identity-based planning and measurement, and outcome-based attribution to broadcast radio at scale.

Broadcast radio, the oldest mass medium in America, just learned how to count.

The Problem That Everyone Knew Existed

Terrestrial radio has always had a marketing problem. Not with listeners — with advertisers. Despite attracting a substantially larger audience than streaming audio, it has historically been limited in its appeal to marketers because of its outdated infrastructure. Broadcast radio is a one-to-many medium with no return path, meaning there is no way to know who is listening at a given moment.

The industry has been trying to solve this problem for years. But the technical challenges were immense. How do you target specific audiences when you have no data on who is actually listening? How do you measure outcomes when you can't track a listener's journey from ear to purchase? How do you attribute a sale when the only signal you have is a broadcast signal?

Advertisers coped by buying demographic buckets: "adults 25-54" or "women 18-49." It was a blunt instrument in an era of surgical precision. Meanwhile, streaming audio, podcasts, and social media ate radio's lunch — not because they had better content, but because they could prove their value.

"The vast majority of audio consumption comes from broadcast radio, yet up until today, it has lacked the targeting and measurement infrastructure available in digital," Lisa Coffey, iHeartMedia's Chief Business Officer, said in a statement.

The gap was not just a technical curiosity. It was a $15 billion revenue problem. Radio has been leaving money on the table for decades.

The Solution: AudioGraph's Three Core Capabilities

AudioGraph is not a single tool. It is a suite of capabilities built around three core functions: targeting, buying, and measurement.

Targeting is the headline. AudioGraph brings digital-like targeting to broadcast radio through custom ID-based audience segments built from first-party listener data and TransUnion's identity graph. These segments inform campaign planning and optimization using privacy-safe AudioGraph IDs, while advanced predictive listening models enable advertisers to reach audiences at scale with greater accuracy than traditional demographic approaches.

The technical architecture is sophisticated. AudioGraph connects a privacy-safe identity spine with enriched audience attributes built from TransUnion data and proprietary ID-level listening models. These models enable planning and measurement at the listener level while activating campaigns at broadcast scale. Because broadcast radio has no return path, Triton engineers built a probabilistic identity model as a workaround — an elegant solution to a problem that has stumped the industry for decades.

Buying is the second pillar. AudioGraph supports multiple buying channels, making broadcast radio as efficient and easy to buy as digital media. The platform offers direct DSP connectivity, ensuring it operates seamlessly with today's digital ecosystem. This means advertisers can purchase radio spots alongside digital, using the same programmatic workflows they already rely on.

Measurement is the third — and possibly most important — capability. AudioGraph was built to be interoperable with the digital measurement ecosystem, supporting any measurement, attribution, or analytics partner that advertisers already work with. iHeartMedia has validated deeper integrations with preferred partners including Magellan AI, PlaceIQ, and GroundTruth, connecting audio exposure to real-world outcomes such as foot traffic and in-store visits.

The early results are striking. Proof of concept shows that broadcast radio campaigns planned and measured using privacy-safe AudioGraph IDs can deliver a KPI outcome 75 percent higher than traditional demo-based plans.

The Scale: 278 Million Listeners, Now Addressable

The numbers behind AudioGraph are staggering. iHeartMedia's broadcast radio stations reach more than 278 million consumers every month. That is 9 out of 10 Americans. It is a scale that few platforms can match. iHeartMedia reaches 9 in 10 Americans every month, delivering national scale that few platforms can match.

Now, for the first time, advertisers can plan, target, measure, and attribute that audience using privacy-safe, ID-informed insights with digital-like precision.

The implications are profound. Advertisers who have been allocating their audio budgets to streaming and podcasting because they could measure it can now access radio's massive audience with the same accountability. Brands that have been avoiding radio because they couldn't prove its ROI now have a tool to do exactly that.

"This innovation plays into the demands of the digital ecosystem and how brands can now buy radio, addressable, measurable and automated," said Vinny Rinaldi, Vice President of Consumer Connections for The Hershey Company. "Radio now has a chance to see its day, helping drive demand creation and new intent, for brands, aligned with the measurement architect of the rest of the digital ecosystem."

The Human Promise: Real Hosts, Real Communities

There is one more layer to AudioGraph that is worth noting. iHeartMedia has made a "Guaranteed Human" commitment: every AudioGraph impression runs alongside content created by real hosts, real creators, and real communities — not AI-generated personalities or synthetic voices.

The promise is both a differentiator and a reassurance. In an era when AI-generated content is flooding the internet, iHeartMedia is betting that the human connection of broadcast radio — the companion that listeners trust — is its most valuable asset.

"We should never forget that broadcast radio is built on a human connection that no technology can replace," Bob Pittman, iHeartMedia's Chairman and CEO, said in a statement. "It turns out that unlike TV, which was just a delivery system for programs, consumers think about radio differently. It's a companion. There are more people listening today than 10 or 20 years ago, and that trust is something no technology can manufacture."

What Comes Next: An Industry-Wide Solution

AudioGraph will launch with iHeartMedia inventory, but the company's ambitions extend far beyond its own stations. Triton Digital created AudioGraph as an industry-wide solution that will be deployed across the broadcast radio landscape in the US and globally. By creating a standardized set of digital signals and data-science-driven models, Triton has enabled AudioGraph as a common identity solution for all radio broadcasters.

The product has been three years in development. Plans to expand its capabilities across the broader broadcast industry in 2027 are already in motion.

The programmatic opportunity is substantial. iHeartMedia expects programmatic revenue to reach roughly $200 million in 2026, up about 50 percent from the roughly $135 million it reported in 2025. The company sees programmatic as one of its biggest long-term opportunities as it integrates its broadcast inventory into the same buying systems it uses for digital campaigns.

The Bottom Line

Broadcast radio has always had the listeners. It has always had the reach. What it has lacked is the infrastructure to prove its value to advertisers. AudioGraph is the infrastructure.

iHeartMedia's new suite of advertising capabilities brings digital-like targeting, identity-based planning and measurement, and outcome-based attribution to broadcast radio for the first time. It connects a privacy-safe identity spine with TransUnion data and proprietary listening models. It offers direct DSP connectivity. It supports any measurement partner. And early proof of concept shows that AudioGraph-powered campaigns can deliver KPIs 75 percent higher than traditional demo-based plans.

The question now is whether advertisers will embrace it. The early signs are promising. Hershey's Vinny Rinaldi called it "a great innovation for the industry." Bob Pittman sees it as a way to "harness trust and unparalleled reach with the precision and proof the modern marketplace demands."

Broadcast radio is the oldest mass medium in America. But on June 18, 2026, it learned a new trick. It learned how to count.
