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.
Between 1952 and 1955, the first home model was introduced by Tappan at $1295 (Â£951), and by 1967 Raytheon released the first counter-top, domestic oven. The 100-volt microwave oven cost just under $500 (Â£366) and was smaller, safer and more reliable than previous models.
