Since the success of her Vocaloid 2 package led to an expansion of marketing possibilities, most of the mass marketing has come after her initial release as a response to her popularity and has been on going since 2008. Even with the addition of other Character Vocals, Miku's name continues to be used as the primary source of marketing for Crypton Future Media, to the point where most products for their Vocaloid related products will usually only feature Hatsune Miku's name. In March 2012, the Nomura Research Institute estimated that the sales of all Hatsune Miku brand goods added up into the region of since her release in 2007. Her name is easily the most recognizable of all Vocaloids.
Vocaloid 2
Megurine Luka was the third and final member of the Character Voice series. She was noteworthy for being the first vocal capable of both English and Japanese speech. She was released on January 30, 2009, and was codenamed "CV03" prior to release. Her English vocal initially did not have a full library and was capable of only 2,200 words, though she was later updated to fix the problem. It is notable that her package was originally going to be called "Hatsune Miku", designed when Vocaloid 2 was first announced to be a bilingual English and Japanese vocal, being the first planned member of the Character Voice series. Her provider is Yū Asakawa.
