In an article titled "Vaporware" in the November 1983 issue of "RELease 1.0", Dyson defined the word as "good ideas incompletely implemented". She described three software products shown at COMDEX in Las Vegas that year with bombastic advertisements. She stated that demonstrations of the "purported revolutions, breakthroughs and new generations" at the exhibition did not meet those claims.
