Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright licenses known as Creative Commons licenses. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators.
Aim and influence
Creative Commons has been described as being at the forefront of the copyleft movement, which seeks to support the building of a richer public domain by providing an alternative to the automatic "all rights reserved" copyright, dubbed "some rights reserved." David Berry and Giles Moss have credited Creative Commons with generating interest in the issue of intellectual property and contributing to the re-thinking of the role of the "commons" in the "information age". Beyond that Creative Commons has provided "institutional, practical and legal support for individuals and groups wishing to experiment and communicate with culture more freely".
Creative Commons works to counter what the organization considers to be a dominant and increasingly restrictive permission culture. According to Lawrence Lessig, founder of Creative Commons, it is "a culture in which creators get to create only with the permission of the powerful, or of creators from the past". Lessig maintains that modern culture is dominated by traditional content distributors in order to maintain and strengthen their monopolies on cultural products such as popular music and popular cinema, and that Creative Commons can provide alternatives to these restrictions.
