Radio still reaches more Americans than almost any other medium. In fact, Nielsen’s new “Everyone. Everywhere.” report gives radio sellers a fresh set of proof points for advertisers.
What We Know: According to Nielsen, radio reaches 92% of U.S. adults each month. That equals more than 242 million consumers. By comparison, TV-connected devices reach 90%, while smartphones reach 87%. Younger listeners are tuning in, too. Radio reaches 87% of adults ages 18 to 34 every month. Additionally, radio and podcasts combined reach 94% of that group. Radio also reaches 92% of Black adults and 93% of Hispanic adults.
The car remains radio’s stronghold. AM/FM claims more than 80% of ad-supported audio time in vehicles, according to Edison Research data cited in the report. Meanwhile, 65% of adult radio listening happens away from home. Nearly three-quarters of that occurs during weekday drive times. Radio and podcasts also dominate buyable audio. Together, they account for 82% of daily ad-supported listening time. Streaming music, by contrast, captures just 16%.
Perhaps most importantly, radio delivers results. Nielsen’s global benchmarks show radio returning $2 for every dollar spent. That ranks second among 10 measured channels, trailing only social media at $2.22. However, marketers ranked radio last among those same channels in perceived effectiveness. Nielsen also highlighted its own measurement. Its Portable People Meter now operates in the 48 largest markets. Additionally, a three-minute listening qualifier, in place since January 2025, raised measured average audience by 24%.
What They Said: “Radio reaches nearly all Americans, in nearly every place they go, on every device. Ease of measurement doesn’t always equal effectiveness. Any in-car data set offered as a standalone basis for buying radio deserves rigorous review.” – Nielsen
What Remains Unclear: Why marketers undervalue radio despite its strong returns isn’t easy to explain or understand for Nielsen or anyone else. The report also didn’t detail if agencies might shift advertising budgets based on these findings.
What It Means: For radio sellers, the information reinforces the medium’s ability to deliver scale and reaches consumers on the move. It also highlights radio’s effectiveness with producing meaningful returns. Those are talking points to use in every advertiser conversation. Still, the perception gap remains the industry’s biggest hurdle. Radio ranks near the top in ROI but last in perceived effectiveness. Consequently, the challenge isn’t proving radio works. It’s convincing buyers to believe the data.
