Unofficial, fan-made music videos ("bootleg" tapes) are typically made by synchronizing existing footage from other sources, such as television series or films, with the song. The first known fan video, or songvid, was created by Kandy Fong in 1975 using still images from Star Trek loaded into a slide carousel and played in conjunction with a song. Fan videos made using videocassette recorders soon followed.[30] With the advent of easy distribution over the internet and cheap video-editing software, fan-created videos began to gain wider notice in the late 1990s.
