NCT (Hangul: ์์ํฐ) is a K-pop boy group produced by S.M. Entertainment. They are named after the Hallyu localization project Neo Culture Technology, a term coined by S.M. founder Lee Soo-man to describe the group's concept of having an unlimited number of members, who would be involved in multiple sub-units based in various cities worldwide.
