Podcast Revolution

Podcasting — on-demand audio content distributed via internet — was enabled technically by RSS feeds and iPods (2004, Dave Winer and Adam Curry created the format) but only reached mass audience after Serial (2014, Sarah Koenig, investigating a 1999 murder case) — the first podcast to achieve viral mass culture penetration, with 175 million downloads. Today 460 million people listen to podcasts globally; the industry is worth $4 billion annually. Podcasting has democratized audio media — anyone with a microphone can publish to a global audience. It has also enabled long-form storytelling and conversation impossible in commercial radio (Joe Rogan's podcast episodes routinely run 3+ hours; Hardcore History by Dan Carlin's episodes can be 6+ hours). Major platforms (Spotify, Apple, Amazon) have invested billions in exclusive podcast content. The medium has spawned new stars (Joe Rogan, Alex Cooper, Lex Fridman) and revived older journalists (Marc Maron, Terry Gross).
