Copyright law is written into the US Constitution, and is based on older laws, starting with the Statute of Anne in England in 1710​. The most recent update to US copyright law is the Sonny Bono Copyright Term Extension Act of 1998, which extended the term of copyright to life of the author plus 70 years​. The purpose of copyright is to encourage and reward people, by providing them certain exclusive rights, to create new works and make them available to the public​:

  • Right to control the reproduction of the work​

  • Right to control the making of derivative works​

  • Right to control the distribution of the work​

  • Right to control the public performance of the work​
