What is Copyright?
“Copyright is a legal concept, enacted by most governments, that grants the creator of an original work exclusive rights to its use and distribution, usually
for a limited time, with the intention of enabling the creator of intellectual wealth (e.g. the photographer of a photograph or the author of a book) to
receive compensation for their work and be able to financially support themselves.
Copyright is a form of intellectual property (as patents, trademarks and trade secrets are), applicable to any expressible form of an idea or information that is substantive and discrete.[1] It is often shared, then percentage holders are
commonly called rightsholders: legally, contractually and in associated "rights" business functions.[citation needed] Generally rightsholders have
"the right to copy", but also 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 other related rights.”
