Eldred -v- Ashcroft (2003)

In this case, the US Supreme Court finally confirmed the provisions of the US Copyright Extension Act 1998. This Act, known as the ‘Sonny Bono’ Act after the late recording artist and congressman, extends US copyright protection to life of author plus 70 years (up from 50 years) and 95 years (up from 75 years) for works owned by corporations. The Act, passed after lobbying from Walt Disney and other media corporations (worried about older works falling into the public domain) returns certain works to copyright and gives extended protection to other works. It could be argued it is the end of public domain as hundreds of thousands of works which would have become freely available are now protected by copyright laws.
