The history of podcasting has rarely been told. But in this episode, the brightest minds in podcasting reveal the inside story of this medium: from the invention of RSS feeds, through the Gold Rush era of corporate investments, to the bubble bursting, and the rise of celebrity podcasts. Along the way, Ira Glass explains the origins of This American Life and Serial, Marc Maron recounts Obama visiting his garage, Roman Mars lays out his vision for indie podcasts, and so much more.
