Radiolab: Mixtape: How The Cassette Changed The World

Before the podcast and the smartphone, there was the cassette tape and the Walkman — two devices that, although not considered much today, were revolutionary. They were recordable, rewritable, spliceable, compact, and mobile. For the first time, they allowed you to move through the world and listen to a voice speaking only to you. These cassette tapes brought us together, pulled us apart, and forever changed how we say those three simple words, ‘I love you.’ In five episodes from around the world, Mixtape explores the impact the cassette had and continues to have today.
