2PM

2PM () is a South Korean boy band formed by JYP Entertainment in 2008 composed of six members: Jun. K (formerly known as Junsu), Nichkhun, Taecyeon, Wooyoung, Junho, and Chansung. Originally a seven-piece group, Jaebeom left the band in 2009. Unlike most Korean boy bands at the time, 2PM constructed a tough and masculine image through their intense performances often featuring acrobatic stunts and sex appeal. As a result, 2PM is known for creating the jimseung-dol (translating to "beast idol" in Korean) phenomenon within South Korea. As the group grew older, they stopped incorporating acrobatics in their choreography routines and transitioned into a more gentlemanly image. The group has achieved commercial success in several regions in Asia, including South Korea, Japan, and Thailand, as a leading figure of the Korean Wave.

Through the reality TV series Hot Blood Men, Korean producer J.Y. Park formed an eleven-member band known as One Day. Eventually, the band was split into the dance-focused group 2PM and the ballad-oriented group 2AM. 2PM debuted with the song "10 Out of 10" on September 4, 2008. They achieved their first number-one single with "Again & Again" in 2009, which contributed to them winning the 2009 MAMA Award for Artist of the Year. Both singles, along with their hit song "Heartbeat", were featured on their debut studio album, 01:59PM (2009), which topped the first issue of the Gaon Album Chart. From 2010 to 2011, they cemented their popularity across Asia with their streak of hit songs: "Without U", "I'll Be Back", and "Hands Up", all of which were included in their second studio album, Hands Up (2011).
