Documentary series. A look at the unsung heroes who allowed us to transport our voices over long distances - one of the greatest transformations in how we live our lives.
The ability to transport our voices over long distances has been one of the greatest transformations in how we live our lives. Innovation expert Steven Johnson traces the unsung heroes of sound, like the printer in France who first recorded the human voice, the maverick inventor who made radio possible through a mistake and the Hollywood star who used the keys of the piano to inspire encrypted messages. Together they helped set off a chain reaction of innovations which have shaped the modern world.
