The microwave oven was invented by Percy Spencer who worked for Raytheon. Raytheon was a technology company at the forefront of its field. It all began with a candy bar melting in Percy’s pocket while he was working with a magnetron, leading him to question the possibilities for its use in the kitchen. More experiments were performed with eggs and popcorn kernels. Then, the focus was to enclose a magnetron to generate electromagnetic waves at the microwave region to create a microwave oven. Raytheon patented the invention in 1945 calling it the Radar Range, which was sold in 1946 for $5,000 each but by 1994 the size and price of microwave ovens had come down enough that they were found in 90 percent of homes. Originally, the microwave oven was 6 feet tall and 700 pounds.18
