Super Junior (슈퍼주니어), also known as SJ or SuJu, is a South Korean boy band formed by SM Entertainment. They made their official debut on November 6, 2005, with the digital single "Twins (Knock Out)" The group currently consists of ten members: Leeteuk, Heechul, Yesung, Shindong, Sungmin, Eunhyuk, Donghae, Siwon, Ryeowook and Kyuhyun.
Super Junior originally debuted with the name Super Junior 05. They were supposed to be a rotational group wherein members will be removed and added regularly. However, this system received criticism from fans. SM Entertainment eventually decided to make them a fixed group and renamed them Super Junior. The group eventually attracted fans, not just in South Korea, but all over the world. Their prominent contributions to the Korean Wave earned them the nickname "King of Hallyu Wave".
Over the years, Super Junior was divided into sub-units, simultaneously targeting different audiences and nationalities. The members have also individually branched out into acting, hosting, and participating in different show formats. Their immense popularity and success as all-rounded entertainers influenced Korean entertainment agencies to train their artists in different aspects of the entertainment industry.
