Audio Advertising in 2025: ROI, Growth & Why Brands Chose Audio
Audio has had a standout year and not just in audience terms. Listening is at record highs, and commercial listening across radio, podcasts and streaming is up 7% year-on-year. Even more telling for marketers: audio advertising revenue has continued to grow at a time when not every cross-platform channel can say the same.
Commercial radio has powered much of that momentum, still representing around 90% of ad-funded audio listening and reaching 40 million people every week. And RAJAR continues to show commercial radio strengthening its position, with Q3 results delivering a record 56% share of listening.
What’s behind the resilience? Audio’s “always on” strength (live, trusted, daily listening) plus the rapid expansion of digital audio; podcasts, visualised content, apps and smart speakers, has created more ways for brands to show up in the moments that matter.
Audio delivers: the ROI story got louder in 2025
A major driver of renewed confidence in audio has been clearer proof of performance.
In September, Radiocentre’s High Gain Audio work (developed with WPP Media, using Thinkbox Profit Ability 2 data covering 141 brands and £1.8bn of spend) separated out broadcast radio and digital audio advertising results. Both outperformed the all-media average for ROI.
Here are the headline figures shared in the research:
- Full-term (two-year) profit ROI
- Digital audio: £5.20 returned for every £1
- Broadcast radio: £5.00 returned for every £1
- All-media average: £4.11
- Short-term (three-month) profit ROI
- Digital audio: £2.70
- Broadcast radio: £2.30
- All-media average: £1.87
There was also a practical planning takeaway: campaigns allocating 15% of total media spend to audio saw a 5% uplift in overall short-term campaign ROI versus campaigns that didn’t include audio.
In plain English: audio isn’t just effective. It’s increasingly measurable, and it punches above its weight when used properly.
Digital audio got smarter (and more targetable)
This year also brought meaningful changes to how advertisers can buy and optimise digital audio — especially across Bauer’s ecosystem.
audioXi: a step-change in addressable audio
Bauer Media Audio UK rolled out audioXi in the UK, designed to use Bauer’s first-party data across its portfolio of audio and publishing brands to help advertisers reach audiences across live radio, podcasts and on-demand listening, with more control and smarter targeting.
audioXi Moments: reaching listeners “in the moment”
Later in the year, Bauer introduced audioXi Moments, adding “in-the-moment” insight-led targeting. The idea is simple but powerful: connect ads to what people are doing right now. For example, aligning to time of day, activity, or mindset, giving brands a more relevant way to land messages.
One line that captured the point perfectly at IAB Upfronts: audio reaches people in moments where other media can’t, commuting, cooking, working, training, unwinding, scrolling, or simply living with a soundtrack on.
Podcasts evolved into “shows” (and brands followed)
Podcasting didn’t just grow. It changed shape.
UK podcast ad spend hit £90m (up 8%) and global forecasts point toward $3bn. But the bigger shift has been consumption: podcasts increasingly live across audio + video + social + live events, which means advertisers now need campaigns designed to travel.
Video podcasts in particular accelerated the move from “episodes” to franchises, talent-led formats with communities, visual identity, and multiple touchpoints for brand partnerships.
Bauer leaned into this “show” era too, with big creator-led launches and a video-first approach showcased across the year from new podcast formats to talent extensions and visualised content built for discovery.
Bauer moments that shaped 2025 (and what they signal for brands)
Beyond industry trends, Bauer’s own 2025 story shows how audio brands build culture, trust and community, the things advertisers can’t buy with targeting alone.
Community impact at scale: Mission Christmas
On 23 December 2025, Mission Christmas announced an incredible £16.9 million raised, supporting 318,767 children, a 10% increase on the 2024 total. Across the campaign, presenters and stations including Hits Radio, Greatest Hits Radio, KISS, Magic Radio and Absolute Radio helped rally listeners nationwide, proving what audio can do when it mobilises communities.
Audience scale + momentum: RAJAR performance
Bauer Media Audio UK’s Q3 2025 RAJAR update reported 22.9m weekly listeners, with strong growth across multiple brands and genres and continued acceleration in connected listening via apps and smart speakers. For advertisers, that’s the sweet spot: mass reach plus more digital listening (and therefore more addressable opportunity).
Brand-building creativity: integrated campaigns and pop-ups
From big entertainment partnerships to innovative formats, Bauer activity across 2025 reinforced a consistent point: audio doesn’t have to be “just a spot.” With the right idea, it becomes branded entertainment that travels across platforms.
Trust, responsibility and the wider media conversation
At Future of Media London (6 November 2025), Bauer Media Advertising MD Simon Kilby took part in a session focused on responsibility, safety and trust in the digital ecosystem, a topic increasingly central to brand suitability and long-term effectiveness. The message for advertisers was clear: where your budget goes shapes the media environment and trusted, regulated spaces matter.
Talent + format evolution
2025 also brought major talent and schedule developments across Bauer brands, from breakfast show changes at KISS (including the Tyler West and Chloe Burrows announcement on 9 December) to Hits Radio’s network strategy and ongoing investment in personality-led content. For advertisers, that matters because distinctive talent drives attention, and attention drives results.
What this means for Hits Radio advertisers in 2026
The direction of travel is clear:
- Audio is growing (and staying central in people’s daily routines).
- ROI evidence is stronger than ever for both broadcast and digital audio.
- Digital audio is more addressable and measurable, without losing the trust and brand safety that make radio powerful.
- Podcasting is now cross-platform, opening up bigger creative canvases for brands.
- Bauer and Hits Radio combine reach, personality and cultural relevance, with the ability to activate across on-air, digital, social and events.
If you’re planning 2026 campaigns, the opportunity isn’t choosing between “radio” and “digital audio” — it’s using both together to build fame, drive response, and show up in the moments your audience actually lives.
