Vuze

Vuze (previously Azureus) is a BitTorrent client used to transfer files via the BitTorrent protocol. Vuze is written in Java, and uses the Azureus Engine. In addition to downloading data linked to .torrent files, Azureus allows users to view, publish and share original DVD and HD quality video content. Content is presented through channels and categories containing TV shows, music videos, movies, video games and others. Additionally, if users prefer to publish their original content, they may earn money from it.

Azureus was first released in June 2003 at SourceForge.net, mostly to experiment with the Standard Widget Toolkit from Eclipse. It later became one of the most popular BitTorrent clients. The Azureus software was released under the GNU General Public License, and remains as a free software application. However, the Vuze software added in more recent versions is proprietary and users are required to accept these more restrictive license terms in order to install current versions of the BitTorrent client.
