abandonware

programvara som inte längre kan köpas, inte längre distribueras, eller vidareutvecklas av upphovsmannen, vanligen äldre än fem år

Abandonware is a product, typically software, ignored by its owner and manufacturer, and for which no support is available. Although such software is usually still under copyright, the owner may not be tracking copyright violations. Within an intellectual rights contextual background, abandonware is a software (or hardware) sub-case of the general concept of orphan works. https://en.wikipedia.org/wiki/Abandonware
