2PM is a six-member boy band from Seoul, South Korea. Originally a seven-member group before leader Jaebeom left due to an internet controversy, they are managed by JYP Entertainment. The current members are Junsu, Junho, Nichkhun, Taecyeon, Wooyoung and Chansung. 2PM is one of the two subgroups branched out from the eleven-member (before Jaebeom's departure) boy band One Day, the other being 2AM. They debuted with the song "10 Jeom Manjeome 10 Jeom" (10점 만점에 10점, lit. 10 Points Out of 10 Points), which showcased their acrobatic and b-boy dance styles. They achieved their first #1 song with "Again & Again".
The members of 2PM all auditioned (except Nichkhun, who was scouted) to become part of JYP Entertainment, to which the Wonder Girls also belong. Some members held their auditions in other countries; for example, Park Jaebeom auditioned in the United States. Other members already had experience in the entertainment industry prior to their acceptance into JYP Entertainment, such as Kim Junsu, who had won various singing competitions, and Ok Taecyeon, Lee Junho and Hwang Chansung, who had participated in the show 'SuperStar Survival'.
2PM's and 2AM's training days were filmed in a documentary called Hot Blood Men, which aired on Mnet. The show documented the rigorous training program of the JYP trainees who were to be part of the group One Day, as well as the elimination of three trainees from the group.

On May 9, 2009, they won their first Mutizen Song award on M!Countdown since their debut; in the same week, they won their second Mutizen on SBS Inkigayo. The group earned their third Mutizen the following week, completing the triple crown and making them ineligible to win for the following weeks. However, the award that had been eluding them - Music Bank - was quickly won soon after. On June 11, 2PM began promotions for "Niga Mipda" (니가 밉다, lit. I Hate You) on M!Countdown. On July 2 and 3, while in Thailand on a promotional tour, 2PM achieved first place on the M!Countdown and Music Bank charts for the song "Niga Mipda". The group thanked its fans for their support through a video made in Thailand posted in their account on Youtube for their win. They achieved the triple crown for the song on M!Countdown by July 16. On July 30, 2PM won the 'Only One Song' award on M!Countdown.
2009: Controversy and departure of Jaebeom
On September 4, 2009, articles surfaced on the internet regarding Jaebeom's posts on his personal Myspace account about his dislike for Korea back in 2005 when he was still a trainee for JYP Entertainment. Jaebeom issued an apology regarding this matter. Although outraged protesters demanded that Jaebeom should be forced out of 2PM, JYP Entertainment CEO Park Jin-young stated on September 7 that he was going to continue to remain part of the group. The following day, Jaebeom announced on his offical fancafe that he would be leaving the group and returning to the United States, with plans of going back to school and bettering his understanding of Music, and also apologized to the other 2PM members for not being a good leader and older brother to the group. Park Jin-young has confirmed that he will respect the singer's decision, and that 2PM will continue on as a 6-member group.
