This fascinating 10 part series takes viewers on a decade-by-decade voyage of discovery through life-changing inventions; like the radio that made the world smaller; the machine gun that made it more dangerous; or the parking metre that made it more expensive. Find out where great ideas come from and meet the brilliant, often quirky minds that bring them to life including the smartest man on the planet and the high school dropout everyone took for a fool. And then there were the not-so-great ideas that mercifully failed; whatever happened to the robo-dog and the air-conditioned business suit? Winners and losers, they were all players in the most innovative century the world has ever known.
