Description

I.O.I (Hangul: 아이오아이; also known as IOI or Ideal of Idol) is a South Korean girl group formed by CJ E&M through the 2016 reality show Produce 101 on MNET. The group is composed of eleven members chosen Lim Na-young (Pledis), Kim Chung-ha (M&H), Kim Se-jeong (Jellyfish), Jung Chae-yeon (MBK), Zhou Jieqiong (Pledis), Kim So-hye (Redline, Sharks & Penguins), Yu Yeon-jung (Starship), Choi Yoo-jung (Fantagio), Kang Mi-na (Jellyfish) , Kim Do-yeon (Fantagio) and Jeon So-mi (JYP). They debuted on May 4, 2016 with the mini-album Chrysalis, and are expected to actively promote either as a whole or as sub-units before returning to their respective agencies. Produce 101 is a survival show where girl trainees from different companies all compete with each other to be in the top 11 to debut. They last for only 1 year due to their contract and being from different companies. They officially disband 31st January 2017. ;(
