The first documented Japanese animation to be distributed in the United States was "The Tale of the White Serpent" airing on March 15, 1961. Until the late 1970s, Japanese community TV stations' broadcasts were aimed exclusive at very young children. Soon after the release video cassette recorders in November 1975, post-"Astro Boy" anime began to spread throughout the United States. By March 1976, TV stations in the United States began broadcasting super robot shows such as "Getter Robo", and due to the availability of VCRs, fans could record these shows to show to their friends. Fred Patten describes his first exposure to anime at the Los Angeles Science Fiction Society (LASFS) in 1976 when he met up with another fan who was an early adopter of Sony's betamax technology. By May 1977 he and a group of fans founded the first anime club in the United States, the Cartoon/Fantasy Organization (C/FO).
