Key Takeaways

  • iHeartMedia reaches 9 out of 10 U.S. adults every month, more than any other media company.
  • AM/FM radio accounts for the majority of all ad supported audio listening, outperforming digital only audio platforms.
  • Audio advertising is more trusted than social and digital ads, driving stronger attention and recall.
  • Campaigns that include audio see stronger performance across digital, social, and video channels.

Why Audio Wins Attention in a Crowded, Algorithm Driven World

Consumers know that algorithms influence what they see and hear, and many say it has made media feel less authentic and less trustworthy.

Audio stands apart because it is created and delivered by real people. Live radio hosts and podcast creators show up daily, speak directly to audiences, and build familiarity over time. This matters because trust is earned through consistency.

Trust directly impacts performance. Audio ads are consistently rated as more trustworthy than ads on social media and digital platforms, giving brands a stronger foundation for message credibility.

How Audio Delivers Massive Reach Without Losing Relevance

Diversifying media only works if the channel can deliver enough scale to actually move a business. In audio, scale is what turns trust and connection into measurable impact.

iHeartMedia reaches 9 out of 10 U.S. adults every month across broadcast radio, podcasts, streaming, social, and live events. That level of reach gives brands the ability to build meaningful frequency across national campaigns while still showing up in local, culturally relevant moments.

Scale matters in audio because trust compounds. The more consistently audiences hear familiar voices and messages, the stronger recall and credibility become. Audio is repeated, lived in listening that builds memory over time. And that’s why reach at this level is so powerful.

Broadcast radio remains the backbone of that scale. According to Edison, AM/FM radio is the #1 most listened to ad supported audio platform for every age group and in every location in the U.S., far surpassing digital only audio platforms. This gives brands mass reach quickly, with the ability to influence not just target consumers, but also the people who influence them.

Podcasts extend that scale even further by adding depth and engagement. iHeartMedia is the No. 1 podcast publisher by audience reach, delivering 177M U.S. downloads, more than the next two publishers combined. That scale allows brands to tap into premium, creator led environments where audiences choose to listen, lean in, and stay engaged.

Together, broadcast radio and podcasts give marketers something increasingly rare: mass reach with human connection. The ability to drive awareness at scale, reinforce messages through trusted voices, and stay culturally relevant in moments that matter.

Scale is ultimately the reason audio advertising really works.

Why Trust Shows Up in the Numbers

Trust directly impacts outcomes.

Audio listeners are more receptive to advertising messages than users on many digital platforms. Audio ads benefit from uncluttered environments, longer attention spans, and trusted delivery through familiar voices.

Broadcast radio is nearly 3X more trusted than social media, and 78% of listeners trust their favorite radio host’s product recommendations. 

Host read ads amplify this effect. Endorsements delivered by radio hosts and podcast creators tap into relationships built over years, not impressions bought in milliseconds. That is why audio influencer and host read formats continue to deliver strong results across awareness, consideration, and action.

In recent research between Omnicom Media Intelligence and iHeartMedia, we learned depth also has an impact, with longer host-read executions generating 2X the recall of 30 second, host-read ads and being associated with faster purchase timelines among listeners already inclined to buy.

How Audio Lifts Performance Across the Entire Funnel

Audio makes digital work better.

Campaigns that include audio see stronger performance across digital, social, and TV, driven by higher awareness, recall, and emotional connection. Audio builds the story, then other channels reinforce it.

  • +83% lift in social performance
  • +109% lift in digital and social engagement
  • +47% lift in branded search activity

Because audio is screen free, it reaches people during moments digital can’t, including commuting, working, and living daily life. These moments matter because attention is higher and distraction is lower.

For marketers under pressure to prove ROI, this is why audio remains a foundational part of high performing media mixes.

Why Live Audio Drives Culture AND Impressions

Culture is built in real time.

Live radio and podcasts create shared moments around music, sports, local communities, and national conversations. These moments drive relevance, familiarity, and emotional resonance. 

Audiences value media created by real people, especially as automation and AI increase elsewhere. 70% of us are using Ai, yet 90% of us say it’s also important to know media was created by a real person.

Audio places brands inside those moment, and that cultural proximity is difficult to replicate in algorithm driven environments.

Why Diversifying Into Audio Advertising Is a Smart Move Right Now

Marketers are navigating fragmentation, declining trust, and rising pressure to deliver results.

Audio offers something increasingly rare. Mass reach, proven trust, and human connection in one channel. It is consistent, scalable, and culturally relevant. And the numbers back it up.

Adding audio to an existing media mix isn’t about chasing a new channel, but rather about investing in one that continues to deliver measurable impact, even as the media landscape shifts.
