Hi, I enjoy karaoke nights with friends because I like to sing, even though I am not a professional.
karaoke" is also used by recording engineers to refer to an instrumental version of a recording,without the vocals 
I did not know that, karaoke was originally developed in japan and can also incorporate interactive games.
Many artists, amateur and professional, perform in situations where a full band/orchestra is either logistically or financially impractical
That's understandable because those things can be expensive. Daisuke Inoue was the man who invented the 1st karaoke styled machine.
Interestingly, primary difference between Karaoke and sing-along songs is the absence of the lead vocalist.
Many karaoke machines also come with technology that changes the pitch of a song to match the singers vocal range.
the late 1960s and into the 1970s, stored audible materials began to dominate the music recording industry 
I have heard that in Japan karaoke was originally considered to be a fad. It's shocking how far it has come and the 1st video game was called karaoke studio.
Its  not to be confused with "lip synching," in which a performer mimes to a previously produced studio recording with the lead vocal
