Raytheon had demonstrated the world’s first microwave oven in 1947, called the “Radarange.” But it was the size of a refrigerator and cost between $2,000-$3,000, making it impractical for household use. Raytheon and the Tappan Stove Company entered into a licensing agreement to make a smaller, more affordable unit. In 1955, the Tappan Company introduced the first domestic model that was the size of a conventional oven and cost $1,300, still out of reach for most households. In 1965, Raytheon bought out Amana Refrigeration and 2 years later, came out with the first countertop microwave oven that cost just under $500. By 1975, microwave oven sales exceeded that of gas ranges.
