Hatsune Miku

If you thought Miley Stewart (Actress Miley Cyrus) creating a fake alter-ego of Hannah Montana for the stage was weird wait until you hear about popular Japanese pop star Hatsune Miku, a holographic female persona with virtually no human being behind her presence on stage. Hatsune Miku is shown as a sixteen year old, 93 pound, 5'2 foot female anime character with blue ponytails and a pencil thin waist. The meaning of her name stands for the 'first sound of the future'. Her personality was created to portray her as an easy-going, fun-loving, energetic and happy girl. She has even been said to have been in a "relationship" with another holographic Vocaloid character named Kaito. 
What is Vocaloid? This is how Hatsune Miku sings. Technically she is a synthesizer application developed by Crypton Future Media which uses Yamaha Corporation's Vocaloid 2 synthesizing technology to produce sound. After the Vocaloid 2 was produced, Crypton Future Media began to develop Vocaloid 3. The creators of Hatsune Miku's music partly come from voice samples from a japanese actress Saki Fujita at different pitches and tones but is then altered and changed by a synthesizer engine to create full words, phrases, and songs. 
This Japanese pop star was officially released on August 31st, 2007 and Crypton promoted her as "an android diva in the near future world where songs are lost". Not too shortly after, Nico Nico Douga a popular Japanese video sharing site began to post Miku's videos and her popularity increased. In October 2011 Crypton posted a letter from the Japanese Minister of Economy onto Miku's facebook fan page addressing her "contributing to the furtherance of the informatization by minister of economy: 

One fan was quoted saying "She's rather more like a goddess: She has human parts but she transcends human limitations. She's the great posthuman pop star". Although I do agree with Lexy on her post about how it is unfair to create a role model that no one can live up to (tiny perfect waist, perfect proportions at 16, floor-length blue hair) there are benefits to a holographic star. For one, she will never die. She is never going to go off stage and get drunk, or get our of a car and flash the paparazzi. She can be seen as the perfect star because she will forever have a perfect image without ever having to opportunity to mess up.
