Vaporware

Vaporware is a term in the computer industry that describes a product, typically computer hardware or software, that is announced to the general public but is never actually released nor officially cancelled. Vaporware is also a term sometimes used to describe events that are announced or predicted, never officially cancelled, but never intended to happen. 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. The word has been applied to a growing range of products including consumer, automobiles, and some stock trading practices. At times, vendors are criticized for intentionally producing vaporware in order to keep customers from switching to competitive products that offer more features.
