StackAdapt has announced a major expansion of its audio advertising capabilities after forming a new integration with iHeartMedia, the largest audio media company in the United States. This collaboration will make broadcast radio along with digital radio, streaming, and podcasts available to advertisers through the StackAdapt platform. It marks an important shift in how marketers can access one of the most influential and enduring media channels in the country.
For years broadcast radio has remained a powerful force in audio entertainment. By opening access to this inventory programmatically through StackAdapt, marketers can now manage both digital and traditional audio formats in one place. The company describes this advancement as a way to remove barriers that previously required separate systems and manual coordination to activate audio campaigns across AM and FM radio and multiple streaming channels. With more automation advertisers can better plan, forecast, purchase, measure, and report on audio activations while benefiting from faster responses and greater precision driven by real time insights.

Greg Joseph, Vice President of Inventory at StackAdapt, explained the importance of this leap forward for advertisers by stating, “Audio has always been a trusted and powerful medium. By making broadcast radio available programmatically, we are transforming one of advertising’s most established channels for the digital era. This integration enables our clients to reach iHeartMedia’s massive listener base with the same speed, efficiency, and transparency they expect from digital.”
StackAdapt has already built a strong reputation in the audio space as shown in its ranking as the number one Audio Advertising Platform on G2 for 2025. The growing demand for solutions that bring audio into a unified digital ecosystem reinforces the importance of a familiar yet influential channel like radio becoming a seamless part of programmatic campaigns.
iHeartMedia reaches around 278 million listeners each month across the United States. Through this partnership, brands using StackAdapt can access that scale using precise targeting options such as first party data, consumer behaviors, and custom audience signals. They can also align radio with other digital formats available in the platform like connected television, digital out of home, and display advertising. The result is a single environment for designing and analyzing full funnel omnichannel strategies without losing the trust and credibility associated with regulated broadcast content.

Political advertisers are also expected to see value as election cycles continue to drive significant demand for broad and reliable voter reach. Programmatic buying now allows campaigns to activate broadcast radio at the national and local levels with accountability and more detailed planning, making this integration particularly timely ahead of 2026.
Lisa Coffey, Chief Business Officer at iHeartMedia, said, “This partnership with StackAdapt makes iHeart’s premium audio experiences more accessible to the programmatic marketplace. We are bringing together the reach and trust of broadcast radio with the agility and precision of programmatic buying. For marketers, it is an opportunity to activate at scale in one of the most engaging and brand-safe environments.”
The collaboration reflects renewed attention on local voices and community driven programming which continue to keep AM and FM radio at the heart of daily listening. According to industry observations radio still represents 64 percent of all daily ad supported audio consumption and remains a central part of life in both homes and vehicles. Smart speaker usage reinforces this trend with AM and FM radio being the most used audio category on Alexa devices and iHeart stations leading those streams. By bringing broadcast radio into the programmatic world StackAdapt is supporting advertisers in reaching audiences wherever they listen while combining the familiarity and broad reach of radio with the flexibility and accuracy of modern digital media.
