本集简介
With over six billion of them across the planet, smartphones have changed the modern world. With rare access to electronics giant Samsung, Hannah uncovers the technological game-changers that have made the smartphone a reality.
She finds out how 1940s comic book hero Dick Tracy inspired the first mobile phone, discovers why the invention of the digital camera led to one of the biggest commercial blunders of all time, and reveals what a 2010 South Korean sausage frenzy can tell us about touchscreens.
