NCT (Hangul: 엔시티) 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.
The group's main sub-unit NCT U made their debut in April 2016 with the singles "The 7th Sense" and "Without You". NCT 127, a unit based in Seoul, debuted in July 2016. A third unit is scheduled for Tokyo, with subsequent units expected to debut in Beijing and Shanghai.
