Downhill Battle is a non-profit organization based in Worcester, Massachusetts. It launched in August 2003 and argues that the four major recording labels have an oligopoly that is bad for both musicians and music culture. They believe that there is an opportunity to change that.
They also believe that filesharing can strengthen the role of independent record labels in the music industry, and they help produce software that helps independent artists and journalists reach a wider audience. The group supports what they call "participatory culture" where everyone is a part of creating and sharing art and music.
They are also known for their projects such as Grey Tuesday, Banned Music, Peer-to-Peer Legal Defense Fund, and more.
The Downhill Battle team also founded the Participatory Culture Foundation (PCF), which is building an independent, internet video platform. PCF also has a set of Participatory Politics projects, including a politics news site and a messageboard service.
