Copyright

                                               Copyright.

Copyright is a legal concept, enacted by most governments, giving the creator of an original work exclusive rights to it, usually for a limited time. Generally, it is "the right to copy", but also gives the copyright holder the right to be credited for the work, to determine who may adapt the work to other forms, who may perform the work, who may financially benefit from it, and otherrelated rights. It is a form of intellectual property (like the patent, the trademark, and the trade secret) applicable to any expressible form of an idea or information that is substantive and discrete.

Copyright initially was conceived as a way for government to restrict printing; the contemporary intent of copyright is to promote the creation of new works by giving authors control of and profit from them. Copyrights are said to be territorial, which means that they do not extend beyond the territory of a specific state unless that state is a party to an international agreement. Today, however, this is less relevant since most countries are parties to at least one such agreement. While many aspects of national copyright laws have been standardized through international copyright agreements, copyright laws of most countries have some unique features. Typically, the duration of copyright is the whole life of the creator plus fifty to a hundred years from the creator's death, or a finite period for anonymous or corporate creations. Some jurisdictions have required formalities to establishing copyright, but most recognize copyright in any completed work, without formal registration. Generally, copyright is enforced as a civil matter, though some jurisdictions do apply criminal sanctions.

Most jurisdictions recognize copyright limitations, allowing "fair" exceptions to the creator's exclusivity of copyright, and giving users certain rights. The development of digital media and computer network technologies have prompted reinterpretation of these exceptions, introduced new difficulties in enforcing copyright, and inspired additional challenges to copyright law's philosophic basis. Simultaneously, businesses with great economic dependence upon copyright have advocated the extension and expansion of their intellectual property rights, and sought additional legal and technological enforcement.

Scope

Copyright may apply to a wide range of creative, intellectual, or artistic forms, or "works". Specifics vary by jurisdiction, but these can include poems, theses, plays and otherliterary works, motion pictures, choreography, musical compositions, sound recordings, paintings, drawings, sculptures, photographs, computer software, radio and televisionbroadcasts, and industrial designs. Graphic designs and industrial designs may have separate or overlapping laws applied to them in some jurisdictions.

Copyright does not cover ideas and information themselves, only the form or manner in which they are expressed.^[18] For example, the copyright to a Mickey Mouse cartoon restricts others from making copies of the cartoon or creating derivative works based on Disney's particular anthropomorphic mouse, but does not prohibit the creation of other works about anthropomorphic mice in general, so long as they are different enough to not be judged copies of Disney's. In many jurisdictions, copyright law makes exceptions to these restrictions when the work is copied for the purpose of commentary or other related uses (See fair use, fair dealing). Meanwhile, other laws may impose additional restrictions that copyright does not — such as trademarks and patents.

Copyright laws are standardized somewhat through international conventions such as the Berne Convention and Universal Copyright Convention. These multilateral treaties have been ratified by nearly all countries, and international organizations such as the European Union or World Trade Organization require their member states to comply with them.

Copyright infringement

Main article: Copyright infringement

Piracy is considered to be the illegitimate use of materials held by copyright. For a work to be considered pirated, its illegitimate use must have occurred in a nation that has domestic copyright laws and/or adheres to a bilateral treaty or established international convention such as the Berne Convention or WIPO Copyright Treaty. Improper use of materials outside of this legislation is deemed "unauthorized edition", not piracy.

Piracy primarily targets software, film and music. However, the illegal copying of books and other text works remains common, especially for educational reasons. Statistics regarding the effects of piracy are difficult to determine. Studies have attempted to estimate a monetary loss for industries affected by piracy by predicting what portion of pirated works would have been formally purchased if they had not been freely available. Estimates in 2007 stated 18.2 billion potential losses in consumer dollars lost as a result of piracy activities in the United States. International estimates suggest losses in the billions throughout the last decade. However other reports indicate that piracy does not have an adverse effect on the entertainment industry.
