As a response to a more restrictive copyright system (Sonny Bono Copyright Term Extension, DMCA), which started to limit the blooming sharing and remixing activities of the web, Lawrence Lessig founded the Creative Commons in 2001. In 2002 the Creative Commons released a set of licenses as tools to enable remix culture, by allowing a balanced, fair enabling release of creative works, "some rights reserved" instead of the usual "all rights reserved". Several companies and governmental organizations adapted this approach and licenses in the following years, for instance flickr, DeviantART and Europeana using or offering CC license options which allow remixing. There are several webpages addressing this remix culture, for instance ccMixter founded 2004.
