The Podosphere's daily intelligence brief for podcast industry operators.

Issue #46 · Friday, October 23, 2026 · 3 min read

IAB Tech Lab finalized its v2.3 measurement guidelines while Podscribe closed a long-standing gap in HLS ad tracking, both signs that the industry's measurement plumbing is catching up to where ad dollars already want to go.

Today: New measurement standard · HLS ads get measurable · Spotify Q3 numbers · Creative lags buying · Canadian network launches

1. IAB Tech Lab finalizes v2.3 measurement guidelines

IAB Tech Lab finalized Podcast Technical Measurement Guidelines v2.3, an update to server-side log-data measurement that clarifies how download, audience and ad-delivery rules apply across both audio and video podcasts. Specifications have moved to GitHub for implementers.

Why it matters: Hosting companies and measurement vendors now have a settled spec to build and certify against for video podcasts, not just audio.

2. Podscribe cracks baked-in HLS ad tracking with ART19

Podscribe built a first-of-its-kind integration with Amazon's ART19 that tracks baked-in ads in HLS-delivered episodes, reporting them in the same dashboards advertisers already use. Daylight Media is the first publisher live on it, and Podscribe is onboarding more ART19 publishers now.

Why it matters: Publishers running HLS shows can finally show advertisers performance data for host-read spots, giving buyers a concrete reason to renew instead of guessing.

3. Spotify's ad business keeps growing, but still trails subscriptions

Spotify's Q3 2026 results showed ad revenue up 10% year-on-year on automated biddable sales and podcast sponsorship gains, while premium subscribers grew 9% to 306 million. Ads remain just 10.7% of total revenue and half as profitable as subscriptions.

Why it matters: Ad sellers should note that even at Spotify's scale, podcast and automated ad growth still can't match subscription economics.

4. AudioStack says podcast creative hasn't kept pace with buying

AudioStack argues podcast ad buying has gotten sophisticated through targeting and programmatic access, but most campaigns still run one generic 30-second spot everywhere. Its DynamicCreative tool builds one base ad and generates dozens to thousands of variants for context, location or offer, delivered through standard VAST tags.

Why it matters: Networks and ad sellers sitting on long-tail inventory can use dynamic creative to make contextually-targeted ad slots actually worth the premium buyers now pay for them.

5. The Walrus builds a Canadian podcast network to grow local share

The Walrus is launching a podcast network in spring 2027 pairing a new flagship show with selected independent Canadian podcasts, hosted on Acast with revenue-sharing for creators. Only 43% of Canadian podcast listening currently goes to Canadian-produced shows, and the network aims to push that past 50%.

Why it matters: Hosting platforms and networks watching for consolidation among independent creators should note Acast's role as the chosen distribution partner.
