CopyleftCopyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, freedoms refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents.
Public domainThe public domain (PD) consists of all the creative work to which no exclusive intellectual property rights apply. Those rights may have expired, been forfeited, expressly waived, or may be inapplicable. Because no one holds the exclusive rights, anyone can legally use or reference those works without permission. As examples, the works of William Shakespeare, Ludwig van Beethoven, Leonardo da Vinci and Georges Méliès are in the public domain either by virtue of their having been created before copyright existed, or by their copyright term having expired.
Free-culture movementThe free-culture movement is a social movement that promotes the freedom to distribute and modify the creative works of others in the form of free content or open content without compensation to, or the consent of, the work's original creators, by using the Internet and other forms of media. The movement objects to what it considers over-restrictive copyright laws. Many members of the movement argue that such laws hinder creativity. They call this system "permission culture".
The Pirate BayThe Pirate Bay (sometimes abbreviated as TPB) is an online index of digital content of entertainment media and software. Founded in 2003 by Swedish think tank Piratbyrån, The Pirate Bay allows visitors to search, download, and contribute magnet links and torrent files, which facilitate peer-to-peer, among users of the BitTorrent protocol. The Pirate Bay has sparked controversies and discussion about , copyright, and civil liberties and has become a platform for political initiatives against established intellectual property laws as well as a central figure in an anti-copyright movement.
Pirate PartyPirate Party is a label adopted by political parties around the world. Pirate parties support civil rights, direct democracy (including e-democracy) or alternatively participation in government, reform of copyright and patent laws to make them more flexible and open to encourage innovation and creativity, use of free and open-source software, free sharing of knowledge (open content and open access), information privacy, transparency, freedom of information, free speech, anti-corruption, net neutrality and oppose mass surveillance, censorship and Big Tech.
Copyright alternativesVarious copyright alternatives in an alternative compensation systems (ACS) have been proposed as ways to allow the widespread reproduction of digital copyrighted works while still paying the authors and copyright owners of those works. This article only discusses those proposals which involve some form of government intervention. Other models, such as the street performer protocol or voluntary collective licenses, could arguably be called "alternative compensation systems" although they are very different and generally less effective at solving the free rider problem.
Creative Commons licenseA Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted "work". A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of a given work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.
Remix cultureRemix culture, sometimes read-write culture, is a term describing a society that allows and encourages derivative works by combining or editing existing materials to produce a new creative work or product. A remix culture would be, by default, permissive of efforts to improve upon, change, integrate, or otherwise remix the work of creators and copyright holders, with or without their permission.
Anti-copyright noticeAn anti-copyright notice is a specific statement that is added to a work in order to encourage wide distribution. Such notices are legally required to host such specific media; under the Berne Convention in international copyright law, works are protected even if no copyright statement is attached to them. However, "anti-copyright" statements typically do not take the form of either sophisticated public copyright licenses or a simple dedication to the public domain; instead, they usually just encourage wide distribution.
Internet censorshipInternet censorship is the legal control or suppression of what can be accessed, published, or viewed on the Internet. Censorship is most often applied to specific internet domains (such as, for example, Wikipedia.org) but exceptionally may extend to all Internet resources located outside the jurisdiction of the censoring state. Internet censorship may also put restrictions on what information can be made internet accessible.
