As electronics became increasingly integrated into the modern household, the design of devices became more important than before. These items were celebrated for their appearance, as plastic, sometimes brightly colored, became a standard material. Philanthropist George R. Kravis II collected modern consumer products throughout his career as a radio broadcasting executive. He has since expanded his trove into an extensive selection of industrial design, the highlights of which are presented in 100 Designs for a Modern World (Skira Rizzoli). Introduced by historian Penny Sparke, the book provides a visual timeline of many of the most significant—and delightful—unions of technology and design from the past century.
