NCT (엔시티) is a South Korean boy group formed by S.M. Entertainment. Their name stands for the Hallyu localization project Neo Culture Technology, a term coined by S.M. Entertainment founder Lee Soo-man to describe the group's concept of having an unlimited number of members divided into multiple sub-units based in various cities worldwide. The group's first unit, NCT U, made their debut in April 2016 with the digital singles "The 7th Sense" and "Without You".
