StackAdapt has announced a new integration with iHeartMedia that will allow advertisers to access iHeartMedia’s audio inventory, including broadcast radio, digital radio, streaming, and podcasts, directly through the StackAdapt platform.
The move aims to streamline how marketers plan and activate audio campaigns by making it possible to plan, forecast, buy, measure, and report on all audio channels within one system. This integration removes manual processes and supports faster decision-making using data across both AM/FM broadcast and digital audio.
“Audio has always been a trusted and powerful medium,” said Greg Joseph, VP of Inventory at StackAdapt. “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.”
In 2025, StackAdapt was recognized as the top audio advertising platform on G2. The ranking highlights increased interest among marketers for integrated solutions that can manage performance and efficiency across various audio channels.
iHeartMedia operates broadcast radio stations that reach 278 million ad-supported listeners monthly throughout the United States. Advertisers using StackAdapt can now target this audience using first-party segments or behavioral data alongside other formats like connected TV (CTV), digital out-of-home (DOOH), and display ads to build comprehensive strategies. Marketers can manage their campaigns in one place while reaching audiences in regulated broadcast environments.
Political advertisers are also expected to benefit from this development as they look for reliable ways to connect with voters during the 2026 election cycle. The partnership is positioned as combining the broad reach of AM/FM radio with programmatic buying capabilities for local and national campaigns.
“This partnership with StackAdapt makes iHeart’s premium audio experiences more accessible to the programmatic marketplace,” said Lisa Coffey, Chief Business Officer for iHeartMedia. “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 companies noted that AM/FM radio accounts for 64% of daily ad-supported audio listening in the U.S., driven largely by local programming popular in rural areas. Additionally, AM/FM Radio is reported as the primary use case for Alexa Smart Speakers in American homes, with iHeart being the most-used service.
The integration is now available to StackAdapt clients across the country.
