In the computer industry, vaporware (or vapourware, see spelling differences) is a product, typically computer hardware or software, that is announced to the general public but is never actually manufactured nor officially cancelled.Vaporware is often announced months or years before its purported release, with development details lacking. Usage of the word has broadened to products such as automobiles. At times, vendors are criticized for intentionally producing vaporware in order to keep customers from switching to competitive products that offer more features.Publications widely accuse developers of announcing products early intentionally to gain advantage over others. Network World magazine called vaporware an "epidemic" in 1989, and blamed the press for not investigating whether developers' claims were true. Seven major companies issued a report in 1990 saying they felt vaporware had hurt the industry's credibility. The United States accused several companies of announcing vaporware early in violation of antitrust laws, but few have been found guilty. InfoWorld magazine wrote that the word is overused, and places an unfair stigma on developers."Vaporware" was coined by a Microsoft engineer in 1982 to describe the company's Xenix operating system, and first appeared in print in a newsletter by entrepreneur Esther Dyson in 1983. It became popular among writers in the industry as a way to describe products they felt took too long to be released. InfoWorld magazine editor Stewart Alsop helped popularize it by lampooning Bill Gates with a Golden Vaporware award for the late release of his company's first version of Windows in 1985. Vaporware first implied intentional fraud when it was applied to the Ovation office suite in 1983; the suite's demonstration was well received by the press, but was later revealed to have never existed.
