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.
Revere Ware
Prior to the sale of Revere Ware to Corning Glass Inc in 1985, the brand offered or had in development four series. The traditional 1400 series continued to sell well. The newly developed 2000 line, for use on the then-new 1980s technology of ceramic- and glass-top stoves, featured heavy aluminum bottoms for good heat transfer. Both the ONXY line and the Micro-Fryer line were released after the sale, but were discontinued almost immediately as they were perceived as being in direct competition with existing products from subsidiaries of Corning.The first series developed and introduced after the Corning Glass inc acquisition was the Proline, a heavy gauge stainless steel product that would go through many arbitrary, minor changes during its run. Minor changes would happen frequently across all their lines, undermining consumer confidence. The Vista series was a reintroduction of the 1400 series, again with minor changes and now sold with glass lids taken from other Corning product lines. The Spectrum series featured aluminum non-stick pans with colored enamel bodies, and were imported from Thailand. only four years after the Vista Line hit store shelves, the Centura series was yet another reintroduction of the traditional 1400 line. The Centura series sold with less expensive materials, being made overseas, and were offered exclusively from Wal-Mart. Most other series introduced were contemporaries of other lines from Corning subsidiaries.
