Microwave oven
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven. It was almost tall, weighed and cost about US$5,000 ($ in dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest. An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS "Savannah". An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($ to $ in dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952. They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($ in dollars), but it did not sell well.
Toastmaster (appliances)
From 1929 until 1980, the brand was owned by McGraw Electric, renamed to McGraw-Edison in 1957. Following a leveraged buyout in 1980 to Magic Chef, the brand changed hands several times and finally went public in 1992 as Toastmaster, Inc. The company, headquartered in Boonville, Missouri, United States, was acquired by Salton, Inc., in 1999. After a series of acquisitions, the brand is now owned by Spectrum Brands, Inc. and is licensed to Select Brands, Inc. Commercial Toastmaster products for the food-service industry are manufactured by The Middleby Corporation. 
Company headquarters were moved from Boonville, Missouri to Columbia, Missouri during the 1970s. Factories were located in Boonville, Missouri, Macon, Missouri, Moberly, Missouri, Kirksville, Missouri, Clarence, Missouri and Laurinburg, North Carolina. Three large warehouse facilities were operated in Columbia, Missouri, too. Product brands included Toastmaster, Manning-Bowman, Edison, Everhot, Bersted, Eskimo fans, Zero fans, Ingram clocks and timers and several others. The Vita-Mix blender was also built under contract with Vita-Mix. Products manufactured during the 1970 and 1980 decades were toasters, griddles, box fans, waffle bakers, sandwich makers, ceiling fans, toaster ovens, convection ovens, bread makers, humidifiers, clocks, timers, etc. Other products marketed by the company in the 1970 and 1980 decades were imported from oversea factories such as mixers, meat slicers, can openers, microwave ovens, oscillating fans, etc. Revenues from a sandwich maker known as the Snackster (originally sold exclusively to Walmart) were significant and lead to the company going public on NYSE in 1992.
