Taeyang was a child actor starting in 5th grade. He was recruited at the same time as G-Dragon, at the age of 13 to play the part of mini Sean in the A-Yo MV. (YB was mini-Sean and mini-Jinu was played by 서현석 (Hyeonsuk) who was in the movie 반올림 (Sharp#) After that, he auditioned to join YG Family, having been impressed by JinuSean. His chosen stage name was YB Taekwon, which is either a reference to JinuSean's Taekwon V album or to the giant robot Taekwon V.

His rapping debut was in YG Family's second album in 2002. In 2003, he participated in Wheesung's second album, rapping on the track Player. He performed with JinuSean, Swi.T, Lexy, Masta Wu, Se7en and YG Family, and took part in Wheesung, Gummy, Se7en and YG Family's One concerts.

He was scheduled to debut with G-Dragon as GDYB (for G-Dragon & YB Taekwon) in 2004, but never debuted or released an album. Hyun Suk announced that their debut was canceled in favor of forming a four-to-six-member group.

Even though he'd previously trained to be a rapper and wanted to become one, he debuted in Big Bang as a singer. He's been studying Japanese for three years, since 2004, in preparation for Big Bang's Japanese debut. After graduating high school, he and G-Dragon decided to take a year off before applying for college. He has been accepted at Daejin University in theater and film for 2008, and has mentioned wanting to become an actor.

His first kiss was during the filming of the Ma Girl music video, when the actress got carried away and kissed him for real.
Hyun Suk mentioned in his messages that Taeyang was going to have a solo single, as a reward for hard work and to make up for being too harsh with Taeyang.
