Karaoke is a form of entertainment in which an amateur singer or singers sing along with recorded music on microphone.The music is typically of a well-known song in which the voice of the original singer is absent or reduced in volume. Karaoke has been a popular form of entertainment beginning first in Japan, then the rest of East Asia, since at least the 1980s, and has since spread to other parts of the world. The karaoke industry started in Japan in the early 1970s when singer Daisuke Inoue was asked by frequent guests in the Utagoe Kissa, where he performed, to provide a recording of his performance so that they could sing along on a company-sponsored vacation. Realizing the potential for the market, Inoue made a tape recorder that played a song for a 100-yen coin. This was the first karaoke machine.Early karaoke machines used cassette tapes but technological advances replaced this with CDs, VCDs, laserdiscs and, currently, DVDs. In 1992, Taito introduced the X2000 that fetched music via a dial-up telephone network.
