query: What company first sold the microwave oven?
passage: Microwave oven
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven.[13] It was almost 1.8 metres (5ft 11in) tall, weighed 340 kilograms (750lb) and cost about US$5,000 ($56,000 in 2018 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.[14] 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 ($19,000 to $28,000 in 2018 dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952.[15] They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($12,000 in 2018 dollars), but it did not sell well.
passage: 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.
