This episode is based around an extract from the audiobook of "Pure Invention." We join in the middle of chapter 5, which is all about the invention of the Walkman. We hear from Matt as he describes a conversation between the two co-founders of Sony, Akio Morita and Masaru Ibuka — a conversation that would lead to the creation of the iconic portable music player that completely redefined how we listen to music today.
