Podcasts go programmatic, and the ad-load question follows

Digital audio drew $8.4 billion in 2025 ad revenue and the share of agencies buying audio programmatically jumped from 41% in 2022 to 82%, with Amazon DSP now carrying SiriusXM, Spotify, Acast and iHeart inventory, while the industry wrestles with the same ad-clutter habits that plagued display.

The crux

Programmatic audio brings scale but reintroduces the ad-load problem, with impression-based buys pushing a single listener past 15 ads per campaign just as Spotify tests a skip-ahead button.

Sell-side read

Acast's Greg Glenday warns publishers not to answer skippable ads with more intrusive formats, recounting the "hostage units" he launched in 2013, because podcasting trades on listener trust and has no margin for overexposure.

Watch

Frequency caps, Podscribe's Drengler called them the whole answer, and whether the 70/30 host-read-to-programmatic mix Oxford Road now sees becomes the industry default.
