Girls Planet 999

''Girls Planet 999: The Girls Saga''; zh, s=少女星球999：少女們的盛典, p=Shàonǚ Xīngqiú 999: Shàonǚmen de Shèngdiǎn; ja, ガールズプラネット999：少女祭典, translit=Gāruzu Puranetto 999: Shōjo Saiten (simply referred to as ''Girls Planet 999'') was a South Korean reality competition show created by Mnet. It premiered on August 6, 2021 and was originally broadcast every Friday at 8:20 PM KST for the first eleven episodes until its finale on October 22, which was broadcast live at 8 PM KST. It was aired on the Mnet channel, IQIYI, AbemaTV, tvN Asia or YouTube depending on the viewer's region.

A production by Mnet's parent company CJ E&M and its subsidiary Studio Take One, as well as in collaboration with game developer and publisher NCSoft, the aim of the competition was to debut a new 9-member K-pop girl group consisting of trainees and idols from China, Japan, and South Korea. Auditions for the competition were held from January to February 2021.

Out of 13,000 applicants, 99 final contestants were selected. These 99 contestants were split equally into three groups; the -Group, -Group and the -Group.

In the finale on October 22, 2021, which was broadcast live, the show announced the final 9 members who would debut as Kep1er.

A second season named ''Boys Planet'' is expected to premiere on February 2, 2023 featuring male trainees.

Concept and format

The "planet" theme of the show was derived from a new collaboration between Mnet and NCSoft's new platform called Universe which is centered around K-pop. It allowed votes from other countries outside of the participating three, and also hosted other promotional content for the show.

The show initially grouped the girls into groups of 3 which were called "cells." An entire cell of girls could be eliminated all at once, hence increasing the risk of elimination. To counteract this, the "Planet Top 9" is introduced. Contestants who are selected or voted to be the Planet Top 9 (designated P1 to P9) can reorganize cells to try and lower the chances of elimination. Cells were disbanded after the first elimination round. At the end of the competition, the top 9 most-voted contestants debuted regardless of nationality.

Promotion and broadcast

The show, as well as its auditions, was first announced on January 11, 2021, through Mnet. Yeo Jin-goo was announced as the show's presenter on June 8, followed by the reveal of the mentors and the name of the show's opening theme later that same month. More promotional clips from the show were broadcast that month on Mnet.

The show's premiere date of August 6, 2021, was confirmed through a teaser video released on July 6, 2021. Another teaser video showcasing the faces of the 99 contestants was released on July 8, along with a promotional poster.

The theme song, “O.O.O (Over&Over&Over),” was released on July 12, 2021, accompanied by a performance by the Korean group with Kim Dayeon as Center. Another version of the performance featuring the Chinese group was released on July 14 with Shen Xiaoting as Center. The Japanese group's version was released on July 16 with Hikaru Ezaki as Center. The full version containing all three groups was released on July 29 during ''M Countdown'', preceded by the contestants' profiles which were released from July 17 to 19 at 10 AM KST for each group. More teasers were released in July and August 2021 leading up to the show's premiere.

The show was available through Mnet in South Korea, iQIYI internationally, AbemaTV and Mnet Japan in Japan, tvN Asia in Southeast Asia, and YouTube in the rest of the world through Mnet's YouTube channel, Mnet K-POP.
