Microwave oven
Japan's Sharp Corporation began manufacturing microwave ovens in 1961. Between 1964 and 1966, Sharp introduced the first microwave oven with a turntable, a feature that promotes convenient even heating of food. In 1965, Raytheon acquired Amana. In 1967, they introduced the first popular home model, the countertop Radarange, at a price of US$495 ($ in dollars).
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.
