It is a large-scale project in which the public (called 'national producers') "produces" a boy band by choosing 11 members among 101 trainees from 54 entertainment companies. The public also chooses the group's concept, debut song, and group name. On June 16, 2017, the season finale was broadcast live, announcing the final 11 members who would debut, as well as the official group name Wanna One.
