104 years later, on July 10, 1974, the United States joined the 1971 revision of the Universal Copyright Convention (“UCC”). Originally adopted in Geneva, Switzerland in 1952, the UCC is one of two principal international copyright conventions, the other being the Berne Convention for the Protection of Literary and Artistic Works. The U.S. has been a member of the UCC since 1955, and a member of the Berne Convention since 1989. From the History of Copyright Timeline at the U.S. Copyright Office.
