Definition — What is Vaporware? 

Vaporware is a term in the computer industry that describes a product, typically computer hardware or software that are marketed heavily in the form of concepts and even have campaigns to raise money to produce them but are still being manufactured or never actually released. The term also generally applies to a product that is announced months or years before its release, and for which public development details are lacking.
