Hatsune Miku
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. The name of "Hatsune Miku" was conceived soon after the Vocaloid 2 announcements, when an English and Japanese vocal were developed for the character. The intended design was delayed and later used for Megurine Luka instead. Miku was intended to be the first of a series of Vocaloids called the ""Character Vocal Series"", which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.
Vocaloid
Vocaloids have also been promoted at events such as the NAMM show and the Musikmesse fair. In fact, it was the promotion of Zero-G's Lola and Leon at the NAMM trade show that would later introduce PowerFX to the Vocaloid program. These events have also become an opportunity for announcing new Vocaloids with Prima being announced at the NAMM event in 2007 and Tonio having been announced at the NAMM event in 2009. A customized, Chinese version of Sonika was released at the Fancy Frontier Develop Animation Festival, as well as with promotional versions with stickers and posters. Sanrio held a booth at Comiket 78 featuring the voice of an unreleased Vocaloid. AH Software in cooperation with Sanrio shared a booth and the event was used to advertise both the "Hello Kitty" game and AH Software's new Vocaloid. At the Nico Nico Douga Daikaigi 2010 Summer: Egao no Chikara event, Internet Co., Ltd. announced their latest Vocaloid "Gachapoid" based on popular children's character Gachapin.
