Do you know where Karaoke came from?
Karaoke was invented by Japanese for about 40 years ago.
Although Japanese people love singing, we are shy to sing infront of many people.
Long time ago, many Japanese people could sing at only drinking bars and the party room that have karaoke machine.
Karaoke was only adult hobby during my childhood age.
However now all generations can sing using karaoke.
And karaoke is very popular for not only Japanese but also all over the world.
You may think that the person who invented Karaoke became super rich.
But he is not rich because he didn't apply the patent.
Indeed it would be a waste not to have patent, but we might thank him.
Because I think that Karaoke would be expanding all over the world rapidly and give us a lot of fun because nobody have patent.
