BTS (Hangul: 방탄소년단; RR: Bangtan Sonyeondan), also known as the Bangtan Boys, is a seven-member South Korean boy band formed by Big Hit Entertainment. On June 12, 2013, they first performed the song "No More Dream" from their initial album 2 Cool 4 Skool and commemorate their debut on June 13, 2013. They won several New Artist of the Year awards for the track "No More Dream", including at the 2013 Melon Music Awards and Golden Disc Awards and the 2014 Seoul Music Awards. The band continued to rise to widespread prominence with their subsequent albums Dark & Wild (2014), The Most Beautiful Moment in Life, Part 2 (2015) and The Most Beautiful Moment in Life: Young Forever (2016), with the latter two entering the U.S. Billboard 200. The Most Beautiful Moment in Life: Young Forever went on to win the Album of the Year award at the 2016 Melon Music Awards.

The group's name, BTS, is an acronym for the Korean expression Bangtan Sonyeondan (Hangul: 방탄소년단; Hanja: 防彈少年團), literally meaning "Bulletproof Boy Scouts". The name was conceptualized with the thought that BTS would block out stereotypes, criticisms, and expectations that aim on adolescents like bullets and protect the values and ideals of today’s adolescents. In Japan, they are known as Bōdan Shōnendan (防弾少年団), which translates similarly. In July 2017, BTS announced that in addition to being known as Bangtan Sonyeondan or Bulletproof Boy Scouts, the acronym would also stand for "Beyond The Scene" as part of their new brand identity. This extended their name to mean "growing youth BTS who is going beyond the realities they are facing, and going forward."
