On October 8, 1945 Raytheon filed a U.S. patent for Spencerâs microwave cooking process, and a prototype was developed for testing. It was almost six feet tall, weighed 670 pounds, and sold for the equivalent of $20,000 in todayâs dollars.
The microwave oven really took off though in the early 70s. Tappan Stove company of Mansfield, Ohio bough a license from Raytheon in 1952 and tried to sell a large, 220 volt, wall unit as a home microwave oven in 1955 for even lower price of $1,295 but it was too early and this oven did not sell well.
