[4] Some of the members had previously lived in the United States: former leader Jaebeom in the Seattle area, Nichkhun in Southern California, while Taecyeon attended middle and high school in Massachusetts before returning to Korea.

[14] A controversy regarding Jaebeom emerged when on September 4, 2009, articles surfaced on the internet regarding his posts from 2005 made on his personal Myspace account, in which he expressed his dislike for Korea while he was still a trainee for JYP Entertainment.

[32] A combined fan meeting and press conference was held two days later with the six remaining members of 2PM and JYP Entertainment CEO Choi Jungwook in attendance.

[35]In May 2010, 2PM also performed at the eighth annual Korea Times Music Festival in Los Angeles, California, and at the Dream Concert which was held in Seoul.

[40] In October 2010, 2PM released their fourth EP, Still 2:00PM,[41] with the lead single "I'll Be Back" staying at number one for two consecutive weeks on KBS' Music Bank.

[43] On October 18, 2PM won the "Most Popular Asian Singer" award at the 10th Annual Mandarin Music Honors held at the Wukesong Arena in China.

The concert tour continued with the group performing in different arenas in seven cities: Taipei, Jakarta, Singapore, Kuala Lumpur, Bangkok, Nanjing, and Hong Kong.

[56] From December 5 until 25, 2011, the group embarked on their "REPUBLIC OF 2PM" Japan Arena Tour, but with all 100,000 tickets being sold out in just one minute, JYP Entertainment announced an additional concert date to be held at Fukuoka.

[57] In its annual sales report for the year 2011, Oricon announced that 2PM was the second best-selling new artist in Japan, being the highest-ranking Korean act beating out SHINee, and ranking just behind the Johnny & Associates group Kis-My-FT2.

This was then followed with the group releasing their fourth Japanese single "Beautiful" and a live concert DVD entitled "Arena Tour 2011 — Republic Of 2PM" on June 6.

[70] A second title track named "A.D.T.O.Y" was released on May 11, 2013, which was later recognized by Billboard magazine, ranking at number 13 in its "20 Best K-pop Songs of 2013: K-Town Picks" list.

[74] On October 16, 2013, 2PM released their eighth Japanese single "Winter Games", which became the group's first chart-topper on the Billboard Japan Hot 100 on its issue dated November 2, 2013.

[75] On January 29, 2014, 2PM released their third Japanese studio album, Genesis of 2PM, consisting of 9 new songs and including the previously-released singles "Give Me Love" and "Winter Games".

[79] The album itself was then released in both physical and digital format on September 15, which was followed with the group's promotional performances on Club Octagon in Gangnam District, Seoul and their appearance on M Countdown.

The concert tour covered 12 cities in 5 countries: Seoul, Bangkok, Beijing, Newark, Rosemont, Grand Prairie, Los Angeles, Guangzhou, Nanjing, Hong Kong, Jakarta, and then concluding at the Mercedes-Benz Arena in Shanghai.

[84] From April 7 until May 31, 2014, 2PM embarked on their "2PM OF 2PM" Japan Arena Tour in support of their album, covering the cities of Osaka, Nagoya, Yokohama, and Tokyo and recording a total of over 150,000 people in attendance.

[92] In support of the album, 2PM embarked on their "2PM ARENA TOUR 2016': GALAXY OF 2PM" which was held from April 13 to June 18, 2016, covering the cities of Nagoya, Fukuoka, Hokkaido, Tokyo and Osaka.

[94] The following day, the group celebrated their eight-year anniversary together, consequently teasing their next comeback by posting individual photos of each member on their official social media accounts.

The group also starred in a reality show on Mnet titled Wild Bunny, in which the members escaped the pressures of stardom by performing ten forbidden activities of idols.

[122] In addition, Taecyeon and Wooyoung have been hosting SBS (Seoul Broadcasting System)'s weekly music show Inkigayo, while Jaebeom and Chansung have also made regular appearances on 'Introducing Star Friends'.

Nichkhun and Wooyoung were also frequent guests on SBS's variety talent show Star King between April and October 2009, with the other 2PM members occasionally joining them.

"[125] In August 2009, 2PM collaborated with the Body Shop in 'Soft Hands, Kind Heart', a worldwide campaign that calls for the protection of children and teenagers against sex trafficking.

[citation needed] November 2009 saw multiple new endorsement deals for the group,[127] the first of which being a commercial and print campaign for Market O's "Real Brownie" pastry.

[128] 2PM is also currently endorsing Paris-Croissant Food Company's Paris Baguette bakery franchise, for which the group recorded a special Christmas song and are featured in a series of commercials with popular Korean actress Kim Tae-hee.

[137][7] During their earlier years, they were primarily known for sex appeal, intense performances and stages that often featured at least one member taking off his shirt, which was unheard of among idol groups at that time.

[142][143][138] NME noted, "The group stood out, thanks to their dynamic, acrobatic choreography and hyper masculine image, which cemented them as K-pop's OG 'beast idols'.

[148] Academic Crystal S. Anderson opined that their later discography strongly leaned towards the R&B genre of "quiet storm" as the group transitioned into a sophisticated and mature masculine concept, beginning with the 2013 album Grown.

[151] MTV Asia stated, "[They] rose to prominence as their catchy lyrics and easy-to-follow dance moves exploded in the early days of YouTube, long predating today's viral TikTok challenges.

"[118] 2PM has been noted for successfully transitioning into a "manband" without overly relying on sex appeal gimmicks such as taking off their shirts, with Melon Music's e-magazine dubbing them "classic K-sexy" during their 2021 comeback from hiatus.

[144][152] The members of Monsta X themselves, as well as of newer idol groups such as Seventeen, SF9 and labelmates Stray Kids have cited 2PM as "role models" for their stage presence and charisma during live performances.
