2PM is a six-member South Korean boy band managed by JYP Entertainment. The current members are Junsu, Nichkhun, Taecyeon,Wooyoung, Junho and Chansung. Jay Park originally led the group but left before release of its first studio album.
The members of 2PM found their start under Korean musician Park Jin Young, who formed an eleven-member band known as One Day. Eventually the band was split into 2PM, and a similar but independent group known as 2AM. 2PM debuted with the song "10 Jeom Manjeome 10 Jeom" (10점 만점에 10점, lit. 10 Points Out of 10 Points), which showcased their acrobatic dance styles. They achieved their first Number 1 single with "Again & Again". Both singles featured on their first studio album, The First Album 1:59PM, released in 2009. The band went on to release another Korean album, known as Hands Up, in 2011. They made their Japanese debut later that year with Republic of 2PM.
