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.
Veg-O-Matic
Veg-O-Matic is the name of one of the first food-processing appliances to gain widespread use in the United States. It was non-electric and invented by Samuel J. Popeil and later sold by his son, Ron Popeil along with more than 20 other distributors across the country, and Ronco, making its début in 1963 at the International Housewares Show in Chicago, Illinois. It was also sold in Australia by Philip Kives, who purchased it from Samuel Popeil and sold it as one of the first products through his own marketing firm, K-tel.
