List of formerly proprietary software

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of notable software packages which were published under a proprietary software license but later released with the source code and a more liberal license. While such software typically becomes free software, open source software or public domain, also other constructs or licenses exist.

In some cases, the company continues to publish proprietary releases alongside the non-proprietary version.
