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.
Megurine Luka
Despite the inclusion of English, Megurine Luka was not aimed at a worldwide audience, instead focused primarily at Japanese producers. In 2010, Luka was ranked as the 3rd most popular Vocaloid product Crypton has sold. In October 2013, Luka's Vocaloid 2 software disappeared off the top 10 products charts as the Hatsune Miku V3 and its bundle package disrupted the chart rankings. Luka had already fallen to 6th place during the 2013 period as a result of the KAITO V3 release, but this was the first time Luka had disappeared from the charts. After the charts began to settle down again, Luka began to occupy the same spot on the charts that the Vocaloid 1 KAITO package previously occupied (6th-8th place), putting the popularity of the product on par with the older product. After the MEIKO V3 release, Luka became the only member of the Vocaloid 2 Character Vocal Series vocals to have a product on the charts, leaving her in 5th place. However, Vocaloid 2 vocals were mostly absent from the rankings in April 2014. By mid-2014, both she and the Vocaloid 2 Kagamine Rin\Len package no longer held constant places in the rankings and were constantly on and off Crypton Future Media sales charts. In March 2015, the Megurine Luka V4x package got the no.1 spot for the sales of all digital instruments on Big Fish Audio. Soon after the V4x package release, she grabbed the Crypton top sales rankings and remained there for April 2015. On May 1, the site updated to reveal the package now in 3rd place behind Hatsune Miku V3.
