Miku is the second Vocaloid2 after Sweet Ann and the first installment in the Vocaloid2 Character Vocal Series by Crypton Future Media released on August 31, 2007. The name of the title and the character of the software was chosen by combining "hatsu" (初, first), "ne" (音, sound), and miku (未来, future). The data for the voice was created by actually sampling the voice of Saki Fujita, a Japanese voice actress. Unlike general purpose speech synthesizers, the software is tuned to create J-pop songs commonly heard in anime, but it is possible to create songs from other genres.

Nico Nico Douga played a fundamental role in the recognition and popularity of the software. Soon after the release of the software, users of Nico Nico Douga started posting videos with songs created with the software. According to Crypton, a popular video with a comically altered software mascot holding a leek, singing Ievan Polkka, presented multifarious possibilities of applying the software in multimedia content creation. As the recognition and popularity of the software grew, Nico Nico Douga became a place for collaborate content creation. Popular original songs written by a user would generate illustrations, animation in 2D and 3D, and remixes by other users. Other creators would show their unfinished work and ask for ideas.

On October 18, 2007, an Internet BBS website reported Hatsune Miku was suspected to be victim of censorship by Google and Yahoo!, since images of Miku did not show up on the image searches. Google and Yahoo denied any censorship on their part, blaming the missing images on a bug that does not only affect "Hatsune Miku" but other search keywords as well. Both companies expressed a willingness to fix the problem as soon as possible. Images of Miku were re-listed on Yahoo on October 19.

A Hatsune Miku manga called "Maker Hikōshiki Hatsune Mix" began serialization in the Japanese manga magazine Comic Rush on November 26, 2007, published by Jive. The manga is drawn by Kei, the original character designer for Hatsune Miku. A second manga called Hachune Miku no Nichijō Roipara! drawn by Ontama began serialization in the manga magazine Comp Ace on December 26, 2007, published by Kadokawa Shoten.
