iHeartMedia launches AudioGraph to bring digital-style targeting to broadcast radio
iHeartMedia has launched AudioGraph, a new identity-based audience targeting and measurement platform for broadcast radio, streaming audio, and podcasts. Developed in partnership with Triton Digital, the platform utilizes first-party listener data and tracking models to align traditional audio with modern digital ad-buying standards.
Key Takeaways
- AudioGraph connects privacy-safe IDs to broadcast radio, enabling outcome-based measurement for store visits and foot traffic via partners like PlaceIQ and GroundTruth.
- Internal testing found campaigns using AudioGraph IDs delivered KPI outcomes 75% higher than traditional demographic-based buying.
- Integrated directly with Yahoo DSP, the platform allows radio inventory to be planned and attributed alongside other digital channels within a unified framework.
- Triton Digital plans to expand the platform beyond iHeartMedia to the broader U.S. and international radio markets beginning in 2027.
Why It Matters
The launch addresses the historical data gap between terrestrial radio and digital audio, transforming broadcast scale into an addressable performance channel. By linking TransUnion identity data to proprietary listening models, iHeartMedia is pivoting away from broad demographic buying toward the higher-margin, proof-of-performance models demanded by modern B2B buyers like Hershey. As broadcast still commands 64% of audio consumption, providing a unified measurement layer across radio, streaming, and podcasts reduces technical friction for omnichannel advertisers. Watch for the 2027 industry-wide expansion, which will signal whether identity-based IDs can truly standardize the fragmented global radio landscape.
Additional Context
The launch of AudioGraph follows a multi-year effort by iHeartMedia to modernize its ad tech stack through its subsidiary Triton Digital, which it acquired in 2021. In late 2025, per Triton Digital and Viant, iHeartMedia struck a deal to make its broadcast inventory available programmatically, a move aimed at closing the gap between audio’s high engagement (20% of media time) and its relatively low share of ad spend (roughly 4%). By early 2026, iHeartMedia also deepened its identity capabilities through partnerships with Optable and The Trade Desk to implement Unified ID 2.0, which reportedly led to a 26% increase in average daily spending from advertisers on its digital inventory. Industry forecasts suggest this shift toward digital-like precision in radio is essential for maintaining revenue stability. Per Madison & Wall (March 2026), programmatic audio spend is expected to reach $1.2 billion in 2026, with automation in the sector projected to climb to 46% by 2030. This transition is being driven by brands the Hershey Company, which have pushed for radio to align with the rest of the digital measurement ecosystem. Furthermore, BIA Advisory Services (December 2025) noted that 'Radio’s Resilience Through Digital Extension' is a defining trend for 2026, as local audio sellers move into geotargeted digital inventory and interactive formats to compete for budgets with CTV and social video. While traditional radio revenue has faced pressure, larger media groups are finding success in digital integration. In the months leading up to the AudioGraph launch, iHeartMedia reported that growth in digital advertising—up 12% in some quarters—is increasingly offsetting declines in core terrestrial sales, per Accio reporting in June 2026. This broader trend toward identity-based solutions is further evidenced by Triton Digital's recent integration of cross-device identity graphs, which helped publishers see a 20% lift in revenue per thousand impressions by making listener profiles more addressable to global buyers.
