Nielsen reports that while some marketers favor digital for perceived efficiency, radio consistently delivers high ROI and superior, broad reach, ranking fourth globally in effectiveness. As of early 2025, radio dominates ad-supported audio with 61%-66% share of time spent, providing a cost-effective, high-trust alternative to digital, especially for reaching audiences 35+.
Key Findings: Radio vs. Digital Advertising
- ROI and Effectiveness: Radio boasts some of the highest ROI globally.
- Reach and Audience: Radio maintains the highest weekly reach among all media platforms, reaching 84% of U.S. adults 18+ and remains stronger than digital for older demographics (89% for adults 50-64).
- Audio Consumption: Radio still commands the majority of ad-supported audio time (61%-66%), with audiences 35+ spending 73% of their listening time with radio.
- Cost Efficiency: Radio offers lower CPMs (cost per thousand impressions) compared to many digital channels.
- The Digital Shift: While radio is strong, ad-supported streaming music is growing rapidly, with a 36.4% year-over-year increase in share, particularly among 18-34 year olds, where radio’s share has seen a 15.7% drop.
- Synergy: Pairing radio with digital maximizes campaign performance, as radio acts as a “top-of-funnel” builder, driving reach that enhances digital conversion efforts.
Key Takeaways for Advertisers
- Don’t Overlook Radio: Marketers tend to overinvest in digital due to perceived measurability, but often miss out on the superior reach and ROI of traditional radio.
- Targeted Demographics: For consumers 35+, radio is essential. For 18-34, a mix of radio (43% share) and streaming (24% share) is becoming necessary.
- High Trust: Radio, especially news/talk formats, maintains high credibility compared to digital alternatives.
