Hatsune Miku debuted in 2007 as the mascot and voicebank for Yamaha's Vocaloid singing synthesizer software, developed by Crypton Future Media. Her synthesized singing, turquoise twin-tails and virtual concerts made her a global icon of Japanese pop culture far beyond the software itself. Fan producers built entire songs around her voice, and short clips of her singing and speaking spread widely through anime communities, video edits and soundboards, where her voice remains instantly identifiable to Vocaloid fans.
