Routledge’s new Companion to Radio and Podcast Studies is a follow up to its Radio Reader: Essays in the Cultural History of Radio, published in 2000--precisely the moment when podcasting began to undermine radio’s audio hegemony. What if the transition from radio to podcasting is a paradigm shift, the new medium posing challenges different from radio, and closer to those faced by journalism, literature, and film? Siobhan McHugh's The Power of Podcasting: Telling Stories Through Sound represents a podcast-first, back to basics approach which approaches podcasting as a process, not a technology.
