Podcasts

Podcasts are episodic, on-demand audio programs distributed via RSS feeds and streaming apps, consumed through podcast players and streaming platforms; they are commonly monetized through host-read sponsorships or ads inserted into episodes either at upload time or dynamically at playback.

Producers host audio files and RSS metadata with hosting providers, directories and apps (e.g., Apple, Spotify) distribute episodes to listeners, and monetization is handled either by direct sponsorships baked into episodes or by ad servers/SSAI that dynamically insert programmatic ads at playback. AdTech components include ad servers, dynamic ad insertion, measurement partners and marketplaces that enable targeting, reporting, and buying of inventory across shows and networks.

Buyers are brands, agencies and DSPs seeking reach or niche audiences; sellers include independent podcasters, podcast networks, publishers, hosting platforms and supply-side ad networks. Market dynamics mix direct-sold, relationship-driven sponsorships (often premium and host-read) with a growing programmatic layer priced by CPM or custom deals, resulting in a fragmented long tail of inventory and a smaller set of high-value, audience-focused premium publishers.
