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.
Bronchiolitis obliterans
In 2007 a heavy consumer of microwaved popcorn was diagnosed by a doctor in Denver with "popcorn lung," the first known case involving a consumer. On 16 January 2008, it was announced that Wayne Watson, a Denver man who developed "popcorn lung" after inhaling fumes from microwaved popcorn, was suing the Kroger grocery store chain and its affiliates. In the lawsuit, filed in U.S. District Court, Watson's attorney claimed that the companies "failed to warn that preparing microwave popcorn in a microwave oven as intended and smelling the buttery aroma could expose the consumer to an inhalation hazard and a risk of lung injury." On 19 September 2012 a jury in U.S. District Court in Denver awarded $2.3 million in actual damages and $5 million in punitive damages to Watson. Defendants included Gilster-Mary Lee, the manufacturer; Kroger, and Kroger's subsidiary Dillons, owners of King Soopers & City Market, a Colorado regional supermarket chain.
