The Unit: Idol Rebooting Project

Idol Rebooting Project: The Unit is a South Korean survival reality show on KBS2. The concept of the show is to form male and female unit groups of nine members each, among idols who had already debuted. The show is aiming to give them a fair chance to demonstrate their talents that they may not have been able to showcase before.

Overview
KBS announced in July 2017 that they had started production of a reality show under the working title The Final 99 Match. On August 2, the show's first teaser was released under the new title The Unit, stylized as The Uni+, which stands for "You and I Plus". The show also launched its official website on the same day along with application forms available for any idols interested in joining to fill in and submit, as well as a bulletin board wherein idol recommendations from anyone can be submitted.

Booting Evaluations
During the Booting Evaluations, members of the audience vote while the contestants perform. The contestants will receive 1 Boot when 15% of the audience votes for them. When 90% of the audience vote for the contestants, which is known as "Super Boot", the whole group will be able to join the show immediately. If the contestants do not receive a "Super Boot", the Mentors will determine whether to pass each performer or not. Contestants who receive at least 1 boot from any of the mentors will be able to join the show. The Booting Evaluations were held at the Kintex Hall 9 in Ilsan between September 29 and October 1, 2017.

Theme Song
It was reported that 126 contestants who passed the Booting Evaluations started filming a music video from October 7 to October 9 as part of a mission. The center group would consist of nine males and nine females, and the most stand-out contestant would be the “center of the center". On October 13, The Unit dropped the music video for the competitors' first challenge "My Turn", which also aired on that day on KBS's Music Bank, featuring Sonamoo's Euijin and IM's Kijoong as the girls' and boys' center respectively.

Voting
The Unit opened up voting at 10 p.m. KST on November 11, and servers crashed approximately 15 minutes later as people rushed to place their votes. Voting for the show would be exclusively done through TMON's website, with only one vote for each TMON ID. Anyone who supported the 126 contestants could participate. Each person would choose nine male contestants to form their own “Uni+ B” and nine female contestants to form “Uni+ G”. Within their top nine choices, the voters would pick their favorite contestant, who would be awarded two votes while the remaining eight would receive one vote. This would mean that each voter would be able to help out a total of 18 contestants to achieve their dreams.

From Episode 11 onward, the voting system underwent a major change. It was announced that the voting would be exclusively done through The Unit official mobile app. Each person would pick only three contestants from “Uni+ B” and “Uni+ G” and was allowed to vote only once per day. The voting period started from 12 p.m KST on 7 January and would be closed at 11.59 p.m KST on 25 January 2018.

On February 24's broadcast of The Units "Special Show", it was announced that UNI+ B's band name will be UNB and UNI+ G's band name will be UNI.T'.
