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.
Vocaloid 3
Hatsune Miku had two releases for the Vocaloid 3 software. The first was a new English vocal released on August 31, 2013. The second release was an update on the Vocaloid 2 vocal, it contained 5 vocals, 4 of which were updated versions of 4 of the 6 Hatsune Miku append package vocals ("sweet", "dark", "solid", "soft"). There were two versions of the software released, one with and one without the English version included. It was released on September 26, 2013. Like Kaito before her, she also came with Piapro Studio.
The missing vocals from the Append package ("light" and "vivid") were originally offered for free as part of an early promo for those who had the Vocaloid 2 version and the Vocaloid 3 version of the Hatsune Miku vocals. They were later sold separately on the Japanese version of the on-line store Sonicwire.
