In the beginning, there was the computer. And it was big. As big as a room. Sometimes as big as a house. Early computers required teams of white-coated scientists to keep them running, yet one of those giant behemoths could not match the computing power of a single microchip today. From the first massive computers to today's nanotechnology, DIGITAL REVOLUTIONARIES offers a guided tour of the history of computers and a celebration of the human ingenuity that led the world from ENIAC to iMAC.
