What Is Copyright?
The purpose of the law of copyright universally, is to grant those who create, produce or author works the exclusive right to do certain acts in relation to their works. This bundle of rights is exclusive to them and others can only perform these acts with the copyright holder’s authority and consent or, of course, when copyright has expired. This exclusive bundle of rights, which is collectively known as "copyright", is a right in property, which is as valuable and palpable (even though copyright technically represents intangible or incorporeal property) as a piece of land (even though it is not real property) or a car!
Historically, copyright is the consequence of the Gutenburg press of four centuries ago and was utilised initially to protect printed matter but has been liberally amended over the last century to include films, sound recordings, photographs, broadcasts and cable programmes.
