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.
Chef America Inc.
Chef America Inc. was the former manufacturer of the popular microwavable snack, Hot Pockets. Chef America is a former closely held corporation, which was formed in the late 1970s by two brothers, Paul and David Merage, of Colorado. Chef America introduced Hot Pockets in the early 1980s. Nestlé acquired the corporation in 2002 for the amount of $2.6 billion. Hot Pockets continued to be manufactured in Englewood, Colorado, Chef America's former headquarters, until 2013, when the corporate headquarters was merged with Nestlé's frozen food corporate office in Solon, Ohio. As of 2016, all Hot Pockets are now produced in Mount Sterling, Kentucky.
