Microwave oven
The development of the cavity magnetron in the UK made possible the production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was first introduced by Tappan in 1955, but these units were still too large and expensive for general home use. Sharp Corporation introduced the first microwave oven with a turntable between 1964 and 1966. The countertop microwave oven was first introduced in 1967 by the Amana Corporation. After Sharp introduced low-cost microwave ovens affordable for residential use in the late 1970s, their use spread into commercial and residential kitchens around the world. In addition to their use in cooking food, types of microwave ovens are used for heating in many industrial processes.
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.
