Based on extensive interviews with scientists, engineers, administrators, and corporate executives who lived the story, Dealers of Lightning takes the listener on a journey from PARC's beginnings in a dusty, abandoned building at the edge of the Stanford University campus to its triumph as a hothouse of ideas that spawned not only the first personal computer, but the windows-style graphical user interface, the laser printer, much of the indispensable technology of the Internet, and a great deal more. It shows how and why Xerox, despite its willingness to grant PARC unlimited funding and the responsibility for developing breakthroughs to keep the corporation on the cutting edge of office technology, remained forever unable to grasp (and, consequently, exploit) the innovations that PARC delivered, and details the increasing frustration of the original PARC scientists, many of whom would go on to build their fortunes upon the very ideas Xerox so rashly discarded.
