Why Has Broadcast Radio Lagged Behind Digital Measurement?

For years, audio has delivered what marketers want most: scale, trust, and deep daily engagement. What it hasn’t consistently delivered is the same level of precision and accountability that digital platforms made standard.

The vast majority of audio consumption (64%) comes from broadcast radio, yet up until today, it has lacked the targeting and measurement infrastructure available in digital.

That gap didn’t reflect a lack of audience value, but instead a lack of technology built specifically for broadcast radio’s unique strengths.

Today, broadcast radio enters a new era, as AudioGraph brings digital precision and measurability to the largest audio audience in America.

What Is AudioGraph?

AudioGraph is iHeartMedia’s suite of advertising capabilities that, for the first time, will bring digital-like targeting, identity-based planning and measurement, and outcome-based attribution to broadcast radio at scale. These capabilities are powered by Triton Digital, the global technology and services leader.

That means advertisers can reach audiences with more precision, measure performance more clearly, and connect campaign activity to real outcomes…all within the trusted environment of iHeart’s voices, creators, and communities.

AudioGraph gives marketers a modern way to buy radio that aligns with how media is planned today, without sacrificing what makes audio different and more human. 

At its core, AudioGraph connects:

• A privacy-safe identity spine
• Enriched audience attributes built using TransUnion data
• Proprietary predictive listening models developed by iHeartMedia

Together, these elements allow advertisers to plan, activate, and measure broadcast campaigns using consistent audience definitions across broadcast, streaming, and podcasts.

That is the power of AudioGraph: Modern media precision, powered by human trust.

• 80% of listeners consider our hosts their friend. 
• 78% trust hosts’ product recommendations.

Unmatched Reach, Now with Accountability

Broadcast radio remains the largest audio platform in America. iHeartMedia’s broadcast stations reach more than 278 million consumers every month, representing 9 out of 10 Americans.  

Until now, that reach came with some tradeoffs. Campaigns were largely bought on age and gender demos, with limited ability to connect exposure to real business outcomes.

AudioGraph changes the equation.

Advertisers can now:

• Activate ID-based audience segments instead of broad demos
• Apply consistent targeting across all iHeart audio inventory
• Measure exposure using the same frameworks they rely on in digital channels

Radio is now fully accountable on its own terms.

A Modern Way to Buy Broadcast Audio

AudioGraph was built to fit how agencies and brands already operate.

The platform supports:

• Direct DSP connectivity
• Automated planning and transaction workflows
• Interoperability with today’s digital buying infrastructure

In early use, iHeartMedia completed its first agentic transaction using AudioGraph, demonstrating that broadcast radio can now be planned and transacted with the speed and efficiency marketers expect from digital media. 

This matters because ease of buying drives adoption. When audio is as easy to activate as it is powerful, it earns its place in modern media plans and can prove success on key brand KPIs and goals.

Measurement Designed for Real World Outcomes

AudioGraph was intentionally built for an open measurement ecosystem. Rather than forcing advertisers into a single reporting framework, AudioGraph supports any measurement, attribution, or analytics partner marketers already work with

During early proof of concept testing, iHeartMedia validated integrations with partners including Magellan AI, PlaceIQ, and GroundTruth. These tests connected audio exposure to real world outcomes such as foot traffic and in store visits for a national home improvement brand. 

The takeaway is simple: audio can now be tied directly to business results, beyond upper funnel awareness.

Guaranteed Human, Built In

Every AudioGraph impression runs alongside Guaranteed Human content, created by real hosts, real creators, and real communities. There are no synthetic voices or AI generated personalities in the iHeartMedia ecosystem. 

"It turns out that unlike TV, which was just a delivery system for programs, consumers think about radio differently. It's a companion," said Bob Pittman, Chairman and CEO of iHeartMedia. "There are more people listening today than 10 or 20 years ago, and that trust is something no technology can manufacture. AudioGraph lets advertisers harness trust and unparalleled reach with the precision and proof the modern marketplace demands."

AudioGraph allows advertisers to harness that trust with the proof and precision the modern marketplace demands.

Built for Today, Designed for the Industry

AudioGraph launches with iHeartMedia’s owned and operated inventory across the top 50 U.S. markets, delivering immediate national scale. 

Longer term, AudioGraph is being developed as an industry solution, with plans to expand beyond iHeartMedia and bring these capabilities to broadcast radio more broadly. 
Ultimately, when audio succeeds, the entire media ecosystem benefits.
