Who discover karaoke-sing along?

Karaoke as we know it was popularized in the 1970s in Japan, but its origins can be traced back to a musician named Daisuke Inoue. Inoue created a machine that allowed people to sing along to recorded music, which he initially used in bars. He is often credited with the invention of karaoke, although the concept of singing along to music predates his invention. The term "karaoke" itself means "empty orchestra" in Japanese, reflecting the format of singing without a live band.
