Magellan AI, the leader in audio advertising intelligence, has announced an expanded partnership with iHeartMedia, the top audio provider in the U.S., to bring broadcast radio attribution to the forefront of media measurement. Previously a preferred partner for iHeartMedia’s digital assets, Magellan AI will now extend its capabilities to broadcast radio, allowing advertisers to evaluate performance across podcasts, streaming, CTV, and linear radio within a single, unified framework.
Unified Attribution: Integrates broadcast radio into the same measurement stack as podcasts, streaming audio, and Connected TV (CTV).
Proprietary Data: Leverages iHeartMedia’s simulcast data to map broadcast listeners to digital outcomes.
Full-Funnel Metrics: Tracks web visits, form fills, leads, and purchases directly tied to radio exposure.
Exclusivity: Attribution reporting powered by this specific data set is available exclusively to iHeartMedia advertisers.
Industry Context: Follows Magellan AI's recent launch of YouTube Measurement (March 2026), further consolidating its position as an all-in-one cross-channel audio intelligence platform.
Historically, broadcast radio has been viewed as a high-reach "top-of-funnel" medium, often lacking the granular attribution found in digital audio. This partnership aims to change that by treating broadcast radio as a measurable performance channel. By utilizing simulcast data, Magellan AI can identify listeners exposed to traditional radio broadcasts and track their subsequent digital actions.
"Advertisers want clearer insight into how every channel contributes to outcomes," said Cameron Hendrix, CEO and Co-Founder of Magellan AI. "Our expanded partnership... brings broadcast radio into the same attribution framework as digital audio, giving brands a more complete view of campaign performance."
The move addresses a growing demand among national brands for "total audio" planning. With iHeartMedia reaching nine out of ten Americans monthly, the ability to see how that massive reach converts into specific business results—such as a purchase or a lead—is a significant leap for the industry.
Lainie Fertick, President of iHeartMedia Insights, noted: "We're providing brands with deeper visibility into how broadcast radio works alongside podcasts, streaming audio, and other channels to drive meaningful results."
This expansion reinforces a broader trend in 2026 toward "Total Audio" measurement. By combining linear reach with digital precision, Magellan AI is helping advertisers move past siloed reporting. This is particularly relevant as audio media becomes increasingly converged, with listeners switching seamlessly between traditional dials and digital streams.
