Seventeen is a South Korean boy band. Formed by Pledis Entertainment, the group consists of thirteen members: S.Coups, Jeonghan, Joshua, Jun, Hoshi, Wonwoo, Woozi, DK, Mingyu, The8, Seungkwan, Vernon, and Dino. Seventeen is considered a "self-producing" idol group, with the members involved in songwriting, music production, and choreographing, among other aspects of their music and performances.
The group debuted on May 26, 2015, with the extended play (EP) 17 Carat, which became the longest-charting K-pop album of the year in the US and the only rookie album to appear on Billboard's "10 Best K-Pop Albums of 2015" list. They have since released five studio albums that have all peaked atop South Korea's Circle Album Chart, alongside a number of EPs in both Korean and Japanese.
