From Wikipedia;
On October 8, 1945 Raytheon filed a U.S. patent for Spencer's microwave cooking process and an oven that heated food using microwave energy was placed in a Boston restaurant for testing. In 1947, the company built the Radarange, the first microwave oven in the world.[3] It was almost 1.8 metres (5.9 ft) tall, weighed 340 kilograms (750 lb) and cost about 5000US dollars each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2000 to US$3000. Raytheon licensed its technology to the Tappan Stove company in 1952. They tried to market a large, 220 volt, wall unit as a home microwave oven in 1955 for a price of US$1295, but it did not sell well. In 1965 Raytheon acquired Amana, which introduced the first popular home model, the countertop Radarange, in 1967 at a price of US$495.

A built-in microwave oven is installed into a cabinet or wall, while a countertop microwave sits on a counter. Built-in microwaves are typically more expensive and require professional installation, but they save counter space and offer a sleeker look. Countertop microwaves are more affordable and portable, but take up counter space.
