NCT (Neo Culture Technology) is a boy band created by SM Entertainment in 2016. The group consists of 21 members but this is constantly changing since the idea is to have an unlimited number of members. NCT consists of Taeil, Kun, Doyoung, Jaehyun, Taeyong, Ten, Mark, Yuta, Winwin, Haechan, Renjun, Jeno, Jaemin, Chenie, Jisung, Johnny, Jungwoo, Lucas, Xiaojun, Hendery, and Yangyang. They are divided into four subgroups: NCT U, NCT 127, NCT Dream and WayV.

Just like their other groups, SM Entertainment has released numerous NCT items, often as part of a larger collection prepared for a concert, tour, or fan meeting.
