IKON

iKON is a boy group under YG ent., who debuted in 2015 after the survival show Mix & Match. They rose to fame in South Korea in 2018 with their hit song, Love Scenario.

As of 2019, B.I, the leader of the group has left due to his drug scandal.

Pre-debut, survival shows
Prior to the group's formation, group leader B.I featured on MC Mong's 2009 song "Indian Boy". He performed with MC Mong at the 2009 SBS Dream Concert, as well as on You Hee-yeol's Sketchbook. Group vocalist Ju-ne also made a pre-debut appearance aged thirteen on the SBS variety show Star King. He also competed on SBS's K-pop Star in 2011.

On 3 January 2011, B.I and Jinhwan joined YG Entertainment as trainees, as did Bobby a week later. The three trained together for a year and formed the basis of what was to become "Team B". On 18 April 2012, Ju-ne and Yunhyeong joined Team B, followed by Donghyuk as the sixth and final member on 5 November 2012.

The group was first introduced in 2013, through the reality survival program Who Is Next:WIN as Team B, consisting of leader B.I, members Bobby, Jinhwan, Junhoe, Yunhyeong and Donghyuk. Team B competed against another group of trainees, known as Team A, for the chance to debut. Through three rounds of public voting, Team B eventually lost to Team A, and continued as YG trainees (Team A debut as Winner.)During the survival show, they released two singles as Team B, "Just Another Boy" and "Climax".

The following year, members Bobby and B.I participated in a rap survival show called 'Show Me The Money 3' while 'Mix&Match' was also being filmed (both shows from Mnet). B.I was eliminated in episode 7, as a top 8 participant, while Bobby eventually became the season's champion. The two members' participation in this program increased public awareness about the rap survival show and gave both a huge popularity boost. Bobby used the money he won to help his family move back to South-Korea.

In June 2014, Team B appeared in the reality survival program Mix & Match, a follow-up to WIN: Who Is Next. The aim of the show was to determine the final lineup of iKon, According to YG Entertainment CEO Yang Hyun-suk, the group's name derives from the intent to become an 'icon for Korea', hence the 'K'. While Bobby, B.I, and Jinhwan were confirmed members, the remaining members of Team B competed against three new trainees; Jung Jin-hyeong, Yang Hong-seok, and Jung Chan-woo, who had previously appeared on Korean television as a child actor. It was reported that 150,000 fans applied to attend the final performance of the show, and before the announcement of iKon's official lineup, YG Entertainment's blog server crashed. The final lineup contained the three remaining members of Team B, with the addition of Chanwoo.

On 15 December 2014, iKon performed as the opening act at Bigbang's Japan Dome Tour 2014-2015 X.
