==Career & History==
After ''Produce 101'', the predebut track "[[Crush]]" was released on April 5th. A music video for the song was released on the same day. However, after small controversies on screen time for the members, the video was taken down and a different version with small changes were uploaded in its place.

I.O.I debuted May 4th, 2016 with EP ''[[Chrysalis]]'' and its title track "[[Dream Girls]]".

On August 9th, 2016 they released their single "[[Whatta Man]]". Only 7 of the original 11 members participated in this single due to some of the members debuting or continuing promotions with groups under their company. [[Kim Sejeong|Sejeong]], [[Kang Mina|Mina]], [[Yu Yeonjung|Yeonjung]], and [[Jung Chaeyeon]] were the members unable to participate.

On January 18th, 2017 I.O.I released their final single, "[[Downpour]]". I.O.I won 1 music show with "Downpour". They officially disbanded, but promised fans they would come back as a group for a reunion in the future.

In September of 2019, there were talks that I.O.I would be having a comeback later in the year. It was said that [[Jeon Somi|Somi]] and [[Yu Yeonjung|Yeonjung]] would be left out of the comeback due to their schedules. However, as time went on, the comeback date was pushed back, [[Choi Yoojung|Yoojung]] went on hiatus, [[Zhou Kyulkyung|Kyulkyung]] announced she would be unable to participate due to her activities in China, and fans' doubt grew.

It has been revealed that the members will reunite on May 4 to celebrate their 5th anniversary called "I.5.I - Yes, I Love It!". However, Kyulkyung and Mina will not attend at the reunion, since Kyulkyung is in China and Mina is filming for a upcoming TV drama.
