The Blue Planet

The most prominent and commercially active work with this title is the 2001 BBC nature documentary series (often treated as a feature film or multi-part production in US distribution). Under the Berne Convention implementation and the 1988 Berne Convention Implementation Act, works created after March 1, 1989, are protected by copyright in the US without the requirement of a copyright notice or renewal. As a 2001 production, it is protected for a term of 95 years from publication or 120 years from creation (as a work for hire). Other historical matches, such as 'Planeta azul' (1966, Spain), would likely be protected under URAA restoration (17 USC § 104A) if they were still under copyright in their source country in 1996, or would fall under the automatic renewal rules for 1964-1977 works. However, the 2001 BBC series is the definitive match for this title in the modern US market. It is currently under active commercial exploitation and licensing by BBC Studios and Discovery Communications.
