NCT, short for Neo Culture Technology, is a South Korean boy band formed by SM Entertainment in 2016. The group is designed as a rotating collective with an unlimited membership, organized into several sub-units that operate in different cities and markets. This structure allows new members to join and participate in project releases across the units.

The main sub-units include NCT U, a flexible lineup that changes with each release; NCT 127, the Seoul-based unit with a relatively stable roster; NCT Dream, originally a youth-oriented unit that later adopted a fixed lineup; and WayV, the China-based unit formed in 2019 under SM's Chinese label. In addition, NCT has pursued full-group projects under the umbrella of NCT 2020 and NCT 2021, bringing members from the various units together for collaborative releases.

NCT has released music across its sub-units, with early attention on The 7th Sense and Cherry Bomb from NCT U and NCT 127, respectively. The Resonance projects in 2020–2021 marked coordinated releases that showcased the ensemble across units, followed by studio albums such as Universe in 2021. The group has achieved international chart presence and awards, contributing to the global expansion of K-pop.

NCT's concept emphasizes flexibility and global reach, with members from multiple countries and languages contributing to a diverse discography. This approach has influenced how K-pop groups can structure large, multi-unit projects and maintain a long-term, evolving lineup.
