Bridging histories of technology, media studies, and aesthetics, Electrographic Architecture forges a critical narrative of the ways in which illuminated light and color have played key roles in the formation of America's white imaginary. Carolyn L. Kane charts the rise of the country's urban advertisements, light empires, and neoclassical buildings in the early twentieth century; the midcentury construction of polychromatic electrographic spectacles; and their eclipse by informatically intense, invisible algorithms at the dawn of the new millennium. Drawing on archival research, interviews, and visual analysis, Electrographic Architecture shows how the development of America's electrographic surround runs parallel to a new paradigm of power, property, and possession.
