The last half of the 20th century been a time of unparalleled technological innovation. The sheer power and mobility that technology has made available to millions of people around the world surpasses anything we could have dreamed of 50 years ago.

Jeffrey Young introduces the dreamers and schemers, the visionaries and moguls, the huge successes and the audacious also-rans whose pioneering efforts shaped the way we live our lives today.
