Hatsune Miku
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.
Miki Furukawa
In 2006 Furukawa released her first solo album, "Mirrors", featuring a mixture of guitar-based rock songs and electronic dance-pop. "Bondage Heart" (2008) pointed in a new direction, with heavy influences from post-punk, psychedelic rock and noise, whereas "Very" (2010) was a mostly electropop-oriented record. In December 2009, software developer AH Software used voice samples from Furukawa to create the Vocaloid voice library SF-A2 Miki. In 2011, Miki Furukawa and former Supercar bandmate Nakamura Koji formed the band called Lama. Lama jump-started their formation with a single entitled "Spell", which has been used as an opening theme for the anime "No. 6". The single "Fantasy" was used as the ending theme for the anime "Un-Go".
