In February, Park Jin-young announced the lineup of the upcoming girl group would feature seven members and be decided through Sixteen, a television competition show that would air on Mnet later that year. The show began on May 5 and ended with Nayeon, Jeongyeon, Sana, Jihyo, Mina, Dahyun and Chaeyoung as the seven Twice members. Later, Park decided to add two more girls into the group, making Twice a nine member group by adding Tzuyu, who was added as the audience favorite due to bring the most popular contestant by the end of the show and Momo, who was added by Park himself since he felt the group needed someone with Momo's performance abilities. Momo had already been eliminated a few episodes before the finale, so the decision was disliked by some fans.
