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.
Zoome
zoome's popularity boomed via Hatsune Miku at the end of 2007. Nico Nico Douga, the fostering site of the voice synthesis software, became involved in a scandal which caused some of its members to move to zoome. Dwango, the owner of Nico Nico Douga, had registered the copyright of a Hatsune Miku song to the copyright management group JASRAC under the name "Dwango", without permission from the song's author, sparking outrage among Vocaloid fans. Sometime before the scandal broke out, ACCA had opened a Vocaloid video hosting circle , which was officially recognized by Hatsune Miku's developer, Crypton Future Media. The scandal on Nico Nico Douga and the official recognition in zoome lured many members away from Nico Nico Douga to zoome. As a result, Hatsune Miku videos became one of the mainstays of zoome, and zoome became a leading competitor able to challenge Nico Nico Douga's monopoly of the video hosting service industry in Japan.
