In media, which includes textual, audio, and visual content, free licensing schemes such as some of the licenses made by Creative Commons have allowed for the dissemination of works under a clear set of legal permissions. Not all Creative Commons licenses are entirely free; their permissions may range from very liberal general redistribution and modification of the work to a more restrictive redistribution-only licensing. Since February 2008, Creative Commons licenses which are entirely free carry a badge indicating that they are "approved for free cultural works".[16] Repositories exist which exclusively feature free material and provide content such as photographs, clip art, music,[17] and literature.[18] While extensive reuse of free content from one website in another website is legal, it is usually not sensible because of the duplicate content problem.
