only received protection under federal statutory copyright if the statutory formalities, such as a proper copyright notice, were satisfied. If this was not the case the work immediately entered into the public domain. In 1834 the Supreme Court ruled in Wheaton v. Peters (a case similar to the 1774 case of Donaldson v Beckett in Britain) that although the author of an unpublished work had a common law right to control the first publication of that work, the author did not have a common law right to control reproduction following the first publication of the work. Early internationalisation The Berne Convention was first established in 1886, and was subsequently re-negotiated in 1896 (Paris), 1908 (Berlin), 1928 (Rome), 1948 (Brussels), 1967 (Stockholm) and 1971 (Paris). The convention relates to literary and artistic works, which includes films, and the convention requires its member states to provide protection for every production in the literary, scientific and artistic domain. The Berne Convention has a number of core features, including the principle of national treatment, which holds that each member state to the convention would give citizens of other member states the same rights of copyright that it gave to its own citizens (Article 3-5). Another core feature is the establishment of minimum standards of national copyright legislation in that each member state agrees to certain basic rules which their national laws must contain. Though member states can if they wish increase the amount of protection given to copyright owners. One important minimum rule was that the term of copyright was to be a minimum of the author's lifetime plus 50 years. Another important minimum rule established by the Berne Convention is that copyright arises with the creation of a work and does not depend upon any formality such as a system of public registration (Article 5(2)). At the time some countries did require registration of copyright, and when Britain implemented the Berne Convention in the Copyright Act 1911 it had to abolish its system of registration at Stationers' Hall. The Berne Convention focuses on authors as the key figure in copyright law and the stated purpose of the convention is "the protection of the rights of authors in their literary and artistic works" (Article 1), rather than the protection of publishers and other actors in the process of disseminating works to the public. In the 1928 revision the concept of moral rights was introduced
