Podcasts Could Be Radio’s Secret Weapon In Reaching Younger Consumers.

Radio and podcasts may compete for listener audio time, but Nielsen says advertisers can reach significantly more young adults when they buy both. In a new report making the case for audio advertising, Nielsen survey data finds that combining radio and podcasts increases audience reach among adults 18–34 from 88% to 94%, underscoring the value of using the two platforms together rather than treating them as competing choices.

The findings are part of Nielsen’s new “Everyone. Everywhere” report, which makes a broader argument for radio’s continued strength in an increasingly fragmented media marketplace. But the report also makes clear that podcasts have become an important part of the advertising equation, particularly when marketers are trying to connect with younger consumers.

Leaning into its ability to measure radio, podcasts and streaming audio together, Nielsen also offers evidence that podcasts can deliver measurable returns for advertisers, even as marketers increasingly favor digital channels that make it easier to track consumer behavior.

Its global advertising benchmarks show podcasts generating a weighted return on investment of $1.49 for every dollar spent, a performance Nielsen says is comparable to television and display advertising. Radio performs even better in the analysis, delivering $2 in advertising returns for every dollar spent. That places it second among ten measured advertising channels, trailing only social media at $2.22.

But ad buyers may be misdirecting their dollars. Nielsen says marketers consistently underestimate radio’s effectiveness. In its research, advertisers ranked radio last among the 10 channels in perceived effectiveness, despite its strong measured returns. Podcasts, meanwhile, offer another way for advertisers to reach consumers through audio while generating returns comparable to established advertising channels.

The report also highlights the combined strength of radio and podcasts in the competition for advertising-supported listening time. Americans spend nearly four hours a day consuming audio, according to Nielsen survey data. Of the ad-supported listening time available to advertisers, radio and podcasts together account for 82% vs. 16% for ad-supported streaming music services.

“An audio plan built without both radio and podcasts misses most of the audience,” Nielsen says in the report.

Nielsen doesn’t provide a separate breakdown of radio and podcast listening shares in the report, which draws on first-quarter 2026 listening data from Nielsen and Edison Research’s Share of Ear survey results. The combined figure nevertheless reinforces the company’s argument that advertisers should consider the full audio marketplace when developing media plans.

Although Nielsen’s report is primarily focused on radio, its inclusion of podcasts reflects the increasingly interconnected nature of audio advertising. It also shows pairing radio with podcasts buy in a media buy allows podcasters to overcome some concerns about scale and reach of a podcast-only plan.

Nielsen reports that radio reaches 92% of U.S. adults monthly, representing more than 242 million consumers. Among adults 18–34, radio’s monthly reach is 87%, according to its first-half 2026 Comparable Metrics data. And radio’s monthly reach extends across demographic groups, including 92% of Black adults, 93% of Hispanic adults and 87% of adults ages 18-34, a group often characterized as primarily digital consumers.

“In the era of constant digital scrolling and fragmented attention, it’s easy for marketers to be lured by the ‘new and next.’ We often prioritize platforms based on how easily we can track a click, sometimes forgetting that ease of measurement doesn’t always equal effectiveness,” the report says. “Yet there is a legacy powerhouse that continues to outperform nearly every other medium in the one metric that matters most: actual human reach. That’s radio.”
