Winner (stylized WINNER) is a South Korean boy group formed by YG Entertainment, introduced through the 2013 survival show “WIN: Who Is Next” and officially debuting in August 2014 with the album 2014 S/S. The group, currently consisting of Kang Seung-yoon, Lee Seung-hoon, Kim Jin-woo, and Mino (with former member Nam Tae-hyun departing in 2016), is noted for members’ involvement in writing and producing much of their own material.
