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).
Heinz
In June 2009, a company PR stunt announced they had introduced the prototype of the world's smallest, portable microwave, the "Beanzawave". The microwave was to appeal to office workers and students and can be powered by a computer via a USB port. The microwave may be used to heat up coffee or tea, or small food items. It is also good for heating up Heinz's hot snack line, Snap Pots, for which it was designed. The prototype was designed by microwave expert, Gordon Andrews and industrial designer, Stephen Frazer.
