A copyright is a type of intellectual property that gives the creator of an original work, or another right holder, the exclusive and legally secured right to copy, distribute, adapt, display, and perform a creative work, usually for a limited time.[1][2][3][4][5] The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself.[6][7][8] A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States.
Some jurisdictions require "fixing" copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders.[9][10][11][12][13][better source needed] These rights normally include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution.[14]
Copyrights can be granted by public law and are in that case considered "territorial rights". This means that copyrights granted by the law of a certain state do not extend beyond the territory of that specific jurisdiction. Copyrights of this type vary by country; many countries, and sometimes a large group of countries, have made agreements with other countries on procedures applicable when works "cross" national borders or national rights are inconsistent.[15]
Typically, the public law duration of a copyright expires 50 to 100 years after the creator dies, depending on the jurisdiction. Some countries require certain copyright formalities[5] to establishing copyright, others recognize copyright in any completed work, without a formal registration. When the copyright of a work expires, it enters the public domain.
The concept of copyright developed after the printing press came into use in Europe[16] in the 15th and 16th centuries.[17] It was associated with a common law and rooted in the civil law system.[18] The printing press made it much cheaper to produce works, but as there was initially no copyright law, anyone could buy or rent a press and print any text. Popular new works were immediately re-set and re-published by competitors, so printers needed a constant stream of new material. Fees paid to authors for new works were high, and significantly supplemented the incomes of many academics.[19]
Printing brought profound social changes. The rise in literacy across Europe led to a dramatic increase in the demand for reading matter.[16] Prices of reprints were low, so publications could be bought by poorer people, creating a mass audience.[19] In German language markets before the advent of copyright, technical materials, like popular fiction, were inexpensive and widely available; it has been suggested this contributed to Germany's industrial and economic success.[19] After copyright law became established (in 1710 in England and Scotland, and in the 1840s in German-speaking areas) the low-price mass market vanished, and fewer, more expensive editions were published; distribution of scientific and technical information was greatly reduced.[19][20]
