Notes

BTS ( bangtan boys ) was formed in 2010 ,, after BIGHIT Entertainment CEO bang Si-hyuk wanted to form a hip-hop group around RM (Kim NamJoon) ,, and underground rapper well known on the music scene in Seoul . At the time ,, physical album sales were on decline and Digital revenues were not yet high enough compensate . Seeing a need for diversified income status ,, Bang decided to form an idol group instead ,, because of the potential for live concert performances and passionate support from fans of such groups . Many trainees Refused to become part of an idol group ,, but J-hope ,, RM ,, and Suga remained . Bang chose to vary from the visual ,, highly regimented idol groups and create one where the members would be individuals rather than an ensemble and free to express themselves . Auditions were held in 2010 with plans to launch the following year . The band members lived together ,, practicing up to 15 hours a day ,, and first performed before a small crowd of industry insiders in 2013 .
