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.
KitchenAid
The first machine to carry the KitchenAid name was the ten-quart C-10 model, introduced in 1918 and built at Hobart's "Troy Metal Products" subsidiary in Springfield, Ohio. Prototype models were given to the wives of factory executives, and the product was named when one stated "I don't care what you call it, but I know it's the best kitchen aid I've ever had!" They were initially marketed to the farmhouse kitchen and were available in hardware stores. But owing to
the difficulty in convincing retailers to take up the product, the company recruited a mostly female sales force, which sold the mixers door-to-door. The C-10 machine was also marketed heavily toward soda fountains and small commercial kitchens, and was also sold under the "FountainAid" and "BakersAid" model names.
In 1922, KitchenAid introduced the H-5 mixer as its new home-use offering. The H-5 mixer was smaller and lighter than the C-10, and had a more manageable five-quart bowl. The model "G" mixer, about half the weight of the "H-5" was released in August 1928. In the 1920s, several other companies introduced similar mixers, and the Sunbeam Mixmaster became the most popular among consumers until the 1950s.
