Vocaloid
Originally, Hiroyuki Ito—President of Crypton Future Media—claimed that Hatsune Miku was not a virtual idol but a kind of the Virtual Studio Technology instrument. However, Hatsune Miku performed her first "live" concert like a virtual idol on a projection screen during Animelo Summer Live at the Saitama Super Arena on August 22, 2009. At the "MikuFes '09 (Summer)" event on August 31, 2009, her image was screened by rear projection on a mostly-transparent screen. Miku also performed her first overseas live concert on November 21, 2009, during Anime Festival Asia (AFA) in Singapore. On March 9, 2010, Miku's first solo live performance titled "Miku no Hi Kanshasai 39's Giving Day" was opened at the Zepp Tokyo in Odaiba, Tokyo. The tour was run as part of promotions for Sega's "Hatsune Miku: Project Diva" video game in March 2010. The success and possibility of these tours is owed to the popularity of Hatsune Miku and so far Crypton is the only studio to have established a world tour of their Vocaloids.
Supercell (band)
Ryo chose to distribute his music on Nico Nico Douga because he liked the website along with its response system, which enables user's comments to appear overlaid on the video screen. Ryo did not originally intend to use Hatsune Miku as the vocalist for his songs, and most members of Supercell did not even know of Miku until after "Melt" gained popularity. Since Ryo did not know any singers, he was recommended by his friends to use Miku, which he thought was a good idea since videos using Miku were already widely being distributed on Nico Nico Douga at the time.
