1TYM (원타임) is a four piece Korean Hip-Hop group that debuted under YG Entertainment in 1998. 1TYM stands for "One Time for Your Mind". Although the group has been on hiatus since 2005 they are still listed as current artists on YG Entertainment's official website.
The group found initial success with their first single and by prominently (unofficially) featuring on fellow labelmates' Jinusean's special album The Real. From the beginning their music was hip-hop oriented with occasional pop singles. However as time progressed they abandoned any pop stylings and fully immersed themselves into Hip-Hop and R&B.
The group went on an indefinite hiatus in 2005 when Oh Jin Hwan started his two-years mandatory military duties. After this, Teddy Park become a producer for YG Entertainment, and Song Baek Kyoung joined YG's co-ed group Moo Ga Dang.
