Vaporware is often announced months or years before its purported release, with few details about its development being released. Developers have been accused of intentionally promoting vaporware to keep customers from switching to competing products that offer more features. "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 that they felt vaporware had hurt the industry's credibility. The United States accused several companies of announcing vaporware early enough to violate antitrust laws, but few have been found guilty. "InfoWorld" magazine wrote that the word is overused and places an unfair stigma on developers.
