Origin of group name:
The league name I.O.I means the ideal of idols.
Team slogan and gesture: The slogan is "Yes! I like it! We are I.O.I, hello everyone! " At the same time as the slogan begins, the thumb and four fingers of the right hand rotate in front of the right shoulder and slide forward to the left shoulder, making the thumb and forefinger gesture of "love". [Note 2].
Since the members of I.O.I are directly elected by "Korean nationals" through voting, and "nationals" are producers, they decide to make debut members and form a group through voting. During the broadcast of the program, they were highly concerned by the Korean audience (during the broadcast of the program, they could vote every day, with a total of about 34 million votes), so they were dubbed "National Women's Group" by the Korean media after their debut.
