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
A package containing 3 Japanese male vocals, Yuu, Kyo, Wil voiced by Minorun (Yuu), Nanox (Kyo) and Maui (Wil). They were released on June 20, 2013. Zola Project Neo was released on September 19, 2013. Yoshitaka Amano who previously had been an artist for the Final Fantasy series had been chosen as the illustrator for the package. The trio was designed to give producers a tool for creating songs that had been inaccessible up until that point. Zola Project were designed to offer the highest quality vocal possible and be accessible for both new and experienced Vocaloid users. Zola Project offered supporting roles for trio and duos, as well as harmonies. The boxart was designed as an "image illustration" and not "character designs" like the boxart for other Vocaloid releases. The voice providers who were sampled were given a different script to read from other vocals recorded and in addition received a half a years worth of vocal training before being recorded. The 3 providers who were chosen for the project were picked from 40 possible candidates. The product also came with a special plug-in for Vocaloid 3 called ""ZOLA_Unison" which is designed to help them sing together.
