No longer can Hollywood live in "splendid isolation." Many sectors of commerce including film seek to expand into the global marketplace, but they do not want to abandon their current practices of US copyright law in order to do so. The Berne Convention of 1886 was the first international agreement for intellectual property protection, but the US didn't join it for over 100 years. Through a process of changing certain copyright laws, the US was able to join the convention while still maintaining a uniquely American form of copyright law. This has led to major expansions in US economies such as film, where Hollywood has been able to increase their profits and distribution many times over thanks, in part, to the unique ways that the United States approached the Berne Convention.
