Little more than a quarter century since its invention, there are now nearly 15 billion microchips in use worldwide -- the equivalent of two powerful computers for every man, woman, and child on the planet. The microprocessor is not only changing the products we use, but also the way we live, and, ultimately, the way we perceive reality!

ONE DIGITAL DAY is the result of a unique project designed to make people aware of the thousands of microprocessors we unknowingly encounter every day. Rick Smolan, creator of the award-winning Day in the Life photography books and the bestseller 24 Hours in Cyberspace, sent 100 of the world's most talented photojournalists around the globe on July 11, 1997. Their mission: to depict intimate and emotional stories of how this tiny chip -- a square of silicon the size of a fingernail, weighing less than a postage stamp -- has transformed our human culture forever.
