In early 1970s. by a Filipino whose name is Roberto del Rosario. He earned a nobel prize for it despite Japan claiming they invented it. The first Karaoke-like system started in the Philippines known as a "minus one music" used by entertainers who went to Japan in late 1960s and in the 1970s. These entertainers saved the instrumental sound on tapes with out song lyrics and they use to play it as they sing as entertainers, that way, they did not have to have a musician or a band to play.
In 1971 Daisuke Inoue, a Japanese musician, took a car stereo, a coin box and a small amplifier and created the first karaoke machine. Karaoke means "empty orchestra" in Japanese, and the term was already in use to describe the house bands that would accompany singing patrons at popular night spots in Japan. Daisuke Inoue was one of those house musicians, until a request from a regular customer paved the way for a worldwide phenomenon.
The karaoke-styled machine was developed in various places in Japan. Japanese engineer Shigeichi Negishi, who ran a car audio system assembly business in Tokyo, made the first prototype in 1967.
