WWO: Podcast Advertising Intention Up 59%
Today’s blog post from Cumulus Media | Westwood One’s Audio Active Group looks at how marketers’ attitudes toward advertising on podcasts had changed over the last 11 years. The blog post notes that “in advance of the first IAB Podcast Upfront in 2015, the Cumulus Media | Westwood One Audio Active Group commissioned Advertiser Perceptions to study agency and brand sentiment on podcast advertising. For the
last 11 years, the study has been reprised annually to track buy-side podcast advertising consideration and intention. The latest Advertiser Perceptions study, conducted in June 2025 with 302 marketers and media agencies, reveals advertiser/agency podcasting usage and interest has reached an 11-year high.” Some of the notable takeaways from this study include: 1) Nine out of 10 marketers and media agencies say they have discussed podcast advertising for potential investment; 2) Podcast advertising consideration surges to an eleven-year high: 74% of brands and agencies say they are likely to consider advertising in podcasts; 3) Podcast spending intention jumps to 69%, an eleven-year record; and 4) 78% of agencies and advertisers currently advertise in podcasts, a 5X increase since the first IAB podcast upfront in 2015.

Podcasting is no longer a niche platform lacking scale. Podcasts deserve a larger role in media plans as opposed to “test and learn” experimental buys. 158 million Americans, 55% of persons 12+, are reached monthly. Among persons 18-34, 18-49, and 25-54, monthly reach is now 65% to 73%; 2) It is feasible to consider shifting TV budgets to podcasting given that podcast 18-34 weekly reach (52%) is as big as TV’s (52%); 3) Brands targeting women should give podcasts a starring role in media plans: Podcast female audiences have hit record highs in habituation and reach; 4) Among male demographics, monthly reach is now in the low 70% range; and 5) Adopt agency media legend Arnie Semsky’s “5% solution” to podcasts: Allocate 5% of digital ad budgets to podcasts. 
One out of three American AM/FM radio listeners are reached monthly by AM radio. From the Edison study: 1) AM/FM radio dominates listening in the car with an 88% share of ad-supported audio; 2) AM/FM radio’s near-90 share of in-car ad-supported audio has been steady as a rock for the last six years; 3) AM/FM radio’s ad-supported shares in the car are dominant across all demographics, even among 18-34s; and 4) ‘Perception’ vs. ‘reality’: Agencies and advertisers underestimate AM/FM radio shares and overestimate Pandora and Spotify audiences (‘Perception’ from Advertiser Perceptions data). MRI Simmons shows Ford owners represent 20% of all U.S. AM radio listeners and are more likely to listen to AM radio. Cumulus chief insights officer Pierre Bouvard comments, “AM stations serve very unique, targeted constituencies and represent many languages and voices. As automobile manufacturers consider eliminating AM radio, it’s important to underscore that the AM dial is one of the most diverse media platforms in the world. Why would we eliminate this variety from the car?” 
“while AM/FM radio represented only 16% of the media budgets, AM/FM radio generated 25% of site and search traffic.” Further, it discovered that “AM/FM radio delivered +58% greater site traffic than its share of spend. In contrast, TV delivered -11% less conversion lift than its share of the budget.” A Nielsen sales effect study of a campaign for a major retailer matched Portable People Meter panel data with credit card data to reveal how TV and AM/FM radio impacted sales. The AM/FM radio-only segment, those consumers only reached by the AM/FM radio campaign, had 3 times the sales lift of the consumers reached by the TV ads. Consumers only exposed to the TV ads generated a +4.6% sales increase. Those who saw both the TV ads and the AM/FM radio ads had a +4.8% sales lift. The segment only exposed to the AM/FM radio ads had an outsized +13.4% increase in sales.
