In a world obsessed with clicks and impressions, radio quietly keeps outperforming flashier channels. A 2025 WPP/Radiocentre analysis of $2.2 billion in media spend across 142 brands found that broadcast radio’s two-year ROI ran 22% above the all-media average, with short-term ROI 23% above average (Radio Advertising Home, 2026). Marketron reports radio campaigns can return as much as $10 for every dollar spent (Marketron, 2026).
The reach explains why. Nielsen’s 2026 Audio Today report shows radio reaches 93% of U.S. adults monthly, and Edison Research’s Share of Ear (Q3 2025) found AM/FM still captures 64% of all ad-supported listening — far ahead of Spotify, Pandora, or YouTube Music combined (Ad Results Media, 2026).
Radio’s edge isn’t just cost, though CPMs of $5–$15 undercut most digital display ($20+). It’s trust and proximity: listeners hear radio in cars, at work, and at home, often at the exact moment they’re deciding where to spend. Nielsen’s own data notes that marketers underrate radio’s effectiveness even as econometric studies rank it among the highest-ROI channels globally.
The numbers are clear — radio isn’t legacy media. It’s underpriced media.
