Cook Today . . . Tomorrow's Way
Microwave ovens were introduced in 1947, using radar technology developed during World War II. Noting that microwave generators created heat, a Raytheon engineer adapted the technology for cooking food; his first experiment was to pop kernels of corn. Manufacturers expected that consumers would use the new ovens to cook meals from scratch in a fraction of the time required for conventional cooking. By 2000, 90 percent of U.S. households had a microwave oven.
