For years, the podcasting industry was powered by youth. The stereotype was clear: podcast creators were young, the listeners were young, and the entire format was shaped by digital-native behaviour. But the newest Edison Research Share of Ear Q3 2025 data paints a dramatically different picture — one that marks the beginning of a profound generational shift in who listens to podcasts and how the audio advertising landscape is evolving.
Podcasting has, quite simply, grown up.
In one of the most striking transformations ever documented in the audio sector, podcast listenership is expanding fastest among 35–64-year-olds, with especially sharp gains among 45–54 and 55–64 demographics. What was once a youth-dominated space has now become a cross-generational mainstream audio powerhouse, reshaping how advertisers, creators, and platforms think about digital audio engagement.
The numbers tell a story that’s difficult to ignore — and even harder to resist. This is no longer the niche format it once was. Podcasting, it seems, has entered its mature era.
The Big Shift: Older Adults Now Driving Podcast Growth
When Edison Research compared 2025’s daily podcast usage to its 2017 baseline, the transformation was unmistakable. Back in 2017, daily listeners were overwhelmingly 18–24-year-olds, representing the youth-led birth of modern podcast culture. Fast-forward to 2025, and the center of gravity has shifted dramatically.
So who’s listening today?
25–44
45–54
55–64
These age groups now form the core of the daily podcast audience. And according to industry experts, this rebalancing isn’t just a trend — it’s a redefinition of the medium.
“The biggest change in daily podcast usage has come from the older demos,” explains Pierre Bouvard, Chief Insights Officer at Cumulus Media/Westwood One. “As those older audiences have walked into podcasts, the median age has soared dramatically.”
And soared it has. Podcasting’s median age:
29 in 2017
34 in 2023
39 in 2025
A decade of demographic aging in just eight years.
Why Are Older Audiences Embracing Podcasts Now?
The rise in older listenership is not random. It’s the result of several converging behavioural and technological trends:
1. Smartphones and smart speakers are now universal
Older consumers who once lagged behind in mobile and digital adoption now engage with smart devices daily, making it easier than ever to access on-demand audio.
2. Audio familiarity from radio
Generations that grew up on AM/FM radio already had the habit of listening to spoken-word audio — podcasts simply modernized the experience.
3. A shift in content
Podcast genres have expanded far beyond comedy and pop culture:
News
Politics
Finance
Self-improvement
Wellness
History
True crime
Documentaries
These are topics traditionally favoured by adults 35+.
4. The rise of long-form storytelling
Older listeners prefer:
In-depth discussions
Expert interviews
Investigative narratives
Thoughtful commentary
Exactly the type of content that now dominates top podcast charts.
5. Advertisers finally investing in older demos
As brands chase older consumers with strong purchasing power, podcasting emerges as an ideal channel — creating a reinforcing loop.
Podcasting Enters Mass-Market Territory
For years, the industry knew podcasting had momentum — but many underestimated its potential to reach truly mass-market scale. Now, it’s officially there.
Bouvard puts it clearly:
“This is an ad format that started among the very young and is now becoming a real mass appeal demographic.”
What makes this milestone remarkable is that podcasting didn’t expand by losing its younger audience. Instead:
Younger listeners remained stable
Older listeners surged
The overall pie expanded dramatically
This dual growth is rare in media, where gains in one demographic often come at the expense of another. Podcasting is now one of the few formats where nearly every age group is increasing consumption simultaneously.
But Even With Aging, Podcasting Is Still Young — Very Young
Despite the older demographic surge, podcasting remains one of the youngest media platforms available.
Compared to other formats:
Podcast listeners are 9 years younger than AM/FM radio’s median listener (48).
They are 17 years younger than viewers of the big three broadcast networks.
And 5 years younger than Netflix viewers.
This puts podcasting in a unique position:
Young enough to attract youth-focused brands
Old enough to attract legacy advertisers
Growing fast enough to appeal to both
Podcasting’s Rising Share of Audio: The Battle for Ears
While the demographic shift is fascinating, the real battleground for the future lies in audio market share.
Edison’s latest data shows:
Podcasts hold 20% of all ad-supported audio share among listeners 18+
AM/FM radio remains dominant at 64%
Music streamers (Spotify, Pandora, Amazon Music, YouTube Music) remain in the low- to mid-single digits
This means podcasts have now:
Mass-market reach
Strong engagement
More time spent per listener
A robust ad-supported ecosystem
Yet radio remains the giant — especially in environments where audio dominates, such as the car.
In the Car: Podcasts Are Growing, But Radio Still Rules
Podcast listening in the car has nudged upward:
7% share of in-car listening
But compare that with:
84% for AM/FM radio (ad-supported)
The car has long been radio’s kingdom — and it remains so.
“When it comes to the car, AM/FM radio remains the queen of the road.” — Pierre Bouvard
Even with advanced dashboards, wireless connectivity, and streaming integration, most drivers still rely on radio for:
Simplicity
Local news
Traffic
Weather
Real-time updates
Music without decision fatigue
Podcasts, however, are steadily gaining a foothold — especially during longer commutes and road trips.
Why Advertisers Are Getting Podcast Strategy Wrong
Despite the industry’s evolution, there remains what Bouvard calls a “massive disconnect.”
A survey from Advertiser Perceptions among 300 media agencies and marketers revealed:
Many advertisers significantly overestimate the reach of streaming music platforms
They wrongly believe Spotify’s reach is on par with AM/FM radio
They assume podcasting’s audience is niche, despite its 20% share of ad-supported audio
This misunderstanding leads to sub-optimal media buys.
Example:
Over-the-air radio has 11 times more share of ad-supported listening than Spotify
Yet buyers often allocate budgets as if they are equal
Another problem:
Digital-only audio plans reach just 12% of Americans daily
Adding podcasts increases reach to 33%
But buyers often ignore this
Even worse:
Without AM/FM in the mix, advertisers miss two-thirds of the country
Bouvard’s message is blunt:
Radio + podcasts = true national scale
Digital-only = leaving money on the table
What This Means for the Future of Audio Advertising
Podcasting’s demographic expansion means:
More purchasing power in the listener base
Higher household incomes
More interest from premium advertisers
Stronger CPMs
Greater brand trust
More cross-platform integration
Larger national advertiser budgets
But radio remains essential for:
Mass reach
In-car dominance
Broad frequency
Geographic saturation
Local activation
Quick impact campaigns
The takeaway? Advertisers who ignore either platform risk major gaps.
Why Older Listeners Matter More Than Ever
The influx of older listeners is a game-changer, because this demographic has:
Higher disposable income
More stable purchasing habits
Greater loyalty to brands
Wider interest in long-form content
Strong affinity for news, finance, and lifestyle topics
Their presence:
Stabilises the audience
Broadens content opportunities
Attracts premium sponsors
Encourages higher production values
Fuels continued industry investment
Podcasting is no longer a “startup” medium. It’s an established, maturing, and diversifying audio ecosystem.
The Bottom Line: Podcasting Has Entered a New Era
The Edison Q3 2025 Share of Ear report makes one thing abundantly clear:
Podcasting is now a mainstream, multi-generational medium — and it’s only getting bigger.
The medium’s evolution is not just about numbers; it’s about narrative:
Once youthful
Now diverse
Increasingly powerful
Unmistakably mass-market
Podcasting has not only grown up — it has taken its place alongside radio, television, and streaming as a core part of the modern media diet.
