2PM (투피엠) is a six-member boy group under JYP Entertainment. They officially debuted on September 4, 2008 with the single album "Hottest Time of the Day".
The group is one of the two subgroups splitted from the eleven-member boy band One Day.
The members of 2PM started when Korean musician Park Jin-young 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.
