Public Domain Software
Free to copy
The ecosystem of freely distributable software that flourished alongside commercial games - from amateur creations to utilities to abandoned software, spread via PD libraries and BBSes.
Overview
Public domain software (PD) was the ecosystem of freely distributable programs that existed alongside commercial software. In gaming contexts, PD encompassed amateur games, utilities, demos, and sometimes abandoned commercial software. Distributed through PD libraries, BBSes, and user groups for minimal copying fees, it created a parallel universe of software where sharing was encouraged rather than prohibited.
