You watch a flawless keynote demo, decide to wait for the product instead of buying a competitor, and then years pass before you learn the software never existed. This deep dive traces the history of vaporware, from a 1982 conversation in which Microsoft engineers admitted to Ann Winblad that Xenix development had halted, to Esther Dyson formalizing the term in her November 1983 newsletter as good ideas incompletely implemented, to Bill Gates receiving a golden vaporware award for Windows 1.0 shipping 18 months late.

We dissect the spectrum of intent, from Ovation Technologies faking an entire office suite demo with a hard-coded slideshow in 1983, to genuine development chaos explained by Brooks’ Law, Ashton-Tate’s forced SQL rewrite of dBase IV, and Duke Nukem Forever’s endless engine changes. Then we look at strategic preannouncing as a weapon: Apple’s 1994 System 7 blocking maneuver against Windows 95, the VisiOn to DESQ to Windows chain reaction, IBM’s System/360 Model 91 and PCjr announcements, and why antitrust law struggles to prove a product was knowingly fake when it was announced.

• How the term spread from Microsoft engineers to Comdex exhaustion to financial and automotive vaporware
• Ovation Technologies’ rehearsed keystroke slideshow and the FOMO psychology that let it fool journalists and investors
• Why adding engineers makes late software later, and how Westwood Studios rebuilt its reputation for shipping on time
• FUD, enterprise procurement cycles, and how a giant’s press release can starve a startup of revenue
• Judge Stanley Sporkin calling the practice deceitful on its face, the 1990 industry council against vaporware, and whether AI and crowdfunding are a new golden age of smoke
