If so, you have witnessed (见证) a period of karaoke time, and the people are entertaining themselves by singing along to recorded music. You don't hear the words. Instead, the words appear on a screen for the singers to follow and sing the words. This form of entertainment originated (起源) in Japan, and the word karaoke means "empty" (kara) and "orchestra" (oke).
Karaoke was invented in the early 1970s in Kobe, Japan. The inventor was a musician named Daisuke Inoue. One day, a businessman asked him for a recording of his music so that he could sing along to it at a business meeting in another town. The recording was so good that the businessman returned and asked for more songs. This gave Inoue the idea of inventing the first karaoke machine.
In its early days, the karaoke machine was found mainly in hotels and restaurants. Singers performed in front of the other customers. A lot of people loved the idea of singing their favourite songs, but didn't feel comfortable singing in front of strangers; so in the 1980s, the karaoke box was born. This was a private (私人) room where people could sing with their friends without other people hearing them. Eventually, karaoke found its way into people's homes as part of home theatre systems.
As technology advanced, karaoke-based video games were created. By 2003, people could also access karaoke services on their mobile phones. This made it possible for music lovers to burst into (突然开始) song at any time, in any place. In some countries today, karaoke machines are even found in cars and taxis for the entertainment of passengers. Karaoke is definitely here to stay, and it will continue to adapt to our changing lifestyles.
