In America, the fandom also began as an offshoot of science fiction fandom, with fans bringing imported copies of Japanese manga to conventions.[14] Before anime began to be licensed in the U.S., fans who wanted to get a hold of anime would leak copies of anime movies and subtitle them to exchange with friends in the community, thus marking the start of fansubs. While science fiction and anime grew fandom in media the Grateful Dead subculture that emerged in the late 1960s-early 1970s created a global fandom around hippie culture that would have lasting impacts on society and technology.[15]
