Steve Jobs and Tony Fadell: Inventing the Future: In this episode, an intimate history of two pocket-sized devices that changed the world, and the two men who created them: Steve Jobs and Tony Fadell. Jobs famously co-founded Apple. In the late 90’s, when the company was failing, he hired a young engineer and designer named Fadell, who created a little device that became known as the iPod. It not only turned Apple’s fortunes around, it transformed the music industry and the experience of listening. Fadell’s next assignment was the iPhone, which changed the nature of communication itself. After leaving Apple, Fadell went on to found Nest Labs, a company that has begun to alter the technology of the home. You’ll hear Tony Fadell’s fascinating personal story, told with all the passion and enthusiasm he brings to his game-changing inventions. And you’ll hear Steve Jobs, speaking as a young man (in 1982) about what it takes to innovate. by What It Takes®
