Produce X 101 (Korean: 프로듀스 X 101) is a 2019 South Korean boy groupsurvival reality show on Mnet and the fourth and final season of the Produce 101 franchise. The public, referred to as "national producers", "produces" a boy band by choosing 11 members among the 101 trainees from 47 different entertainment companies and independent trainees through online voting and live voting with multiple elimination rounds. The public will also choose the group's concept, debut song, and group name. The show aired from May 3 to July 19, 2019. Contestant Kim Yohan from Oui Entertainment obtained the most votes at the end, becoming the debut group center.[1][2][3] The group from this show was named X1, but after extensive voting manipulation was proven, the group was disbanded on January 6, 2020.
Promotions and broadcast
On February 28, 2019, Mnet announced that the debuting group under the show will promote for five years, with a 2+1⁄2-year exclusive contract and another two-and-a-half-year non-exclusive contract, meaning that the eventual members can return to co-promote with their original agencies after the first half.[4]
Filming for the show began on March 4, 2019. On the same day, the trainers were announced,[5][6][7] as well as Lee Dong-wook announced as MC role.[8] The trainees were first revealed through a runway show on March 20, 2019.[9] On March 21, their first performance of their title track, "X1-MA" (Korean: _지마) was revealed on M Countdown later that day, revealing Son Dong-pyo of DSP Media as the center.[9]
The show premiered on May 3, 2019, on Mnet in South Korea, Mnet Japan and AbemaTV in Japan, JOOX in Thailand, Hong Kong, Malaysia, Myanmar and Indonesia, YouTube and Vlive in Other international location.

New to this series is the X rank, the lowest rank where the contestants are at their most vulnerable to be eliminated. It is similar to the F rank used in the previous three seasons. Furthermore, the 11th member of the final group will be decided by the total number of votes they have accumulated throughout the whole season, meaning that the trainee who places 11th in the finale does not necessarily become the 11th member of the final group.

Several viewers suspected that Mnet had tampered with the total votes after noticing numerical patterns in the final episode. In response to the allegations, Mnet admitted that there were errors in calculating, but they also maintained that final rankings were correct and had no intention of changing X1's member line-up.[17] 14 representatives from entertainment agencies of the 20 finalists held a meeting on July 29, 2019, and agreed to support Produce X 101's outcome and X1's debut.[18]
On August 1, 2019, 272 viewers filed a lawsuit against Mnet for electoral fraud, as their on-site text voting service charged ₩100 per vote.[19][20] Politician Ha Tae-kyung also condemned Mnet, stating that some of the numbers had a low probability of naturally occurring.[20][21] On August 20, 2019, a search warrant was issued on CJ E&M offices and a text voting company by the Seoul Metropolitan Police Agency.[22] During their first search, the police uncovered voice recordings of the staff members discussing vote manipulation on the previous seasons of the show, resulting in them extending their investigation to all four seasons of the Produce 101 series,[22]Idol School,[22][23]Show Me the Money, and Superstar K.[24] Several brands cancelled their endorsement deals with X1 or put them on hold.[25] In spite of this, X1's debut proceeded as planned.[26]
On October 1, 2019, the Seoul Metropolitan Police Agency confirmed that votes from the eliminated trainees were added to the total votes of the members who debuted in X1, a process that affected 2-3 trainees who were originally in the top 11.[27] The police issued a search and seizure warrant on the offices of Starship Entertainment, Woollim Entertainment, and MBK Entertainment.[28][29][30] The police also investigated several agencies involved in Produce 48.[31] Reportedly, per contract signed with CJ E&M, the entertainment agencies were paid ₩100,000 for every episode their talent appeared in. An anonymous trainee alleged only ₩1 million was given to their talent agencies for participating in a song, while each participant would only get a small percentage, and CJ E&M would keep additional profits if the song performed well. Some entertainment agencies who disagreed would request their talents to be eliminated at the last minute to withdraw them.[32]
On October 15, 2019, MBC broadcast a feature on the vote rigging controversy on PD Note.[33] Participants of Produce X 101 and Idol School and agency officials alleged anonymously that the production teams were biased to trainees they preferred, such as forcing song producers to give certain trainees more lines and providing them with more screen time.[33][34] An anonymous trainee alleged that one trainee, under pressure from Starship Entertainment,[35] was secretly informed about a mission in advance by one of the choreographers.[34] He also alleged that some trainees knew the final rankings before the results were announced, and that a trainee from Woollim Entertainment was told by a team leader that only one person from their company would debut in X1.[36]
Two trainees alleged that the center position for the theme song, "X1-MA", was originally assigned to a different contestant chosen by trainee vote before the producers changed it to audience vote it at the last minute.[33][37][38] A fourth trainee claimed that many participants felt the show was biased towards trainees from Starship Entertainment.[36][35] Staff members anonymously alleged that, for the final ranking results, only one off-site producer had counted the votes in a separate room and sent them the results via text message.[38] Following the report, on October 16, 2019, the police began investigating whether the producers had accepted money for manipulating the votes.[39] On October 17, 2019, Korea Communications Standards Commission revealed that they may fine Mnet up to ₩30 million for violating the Enforcement Decree of the Broadcasting Act.[40]
On November 5, 2019, after approval from the Seoul National District Court, the police issued arrest warrants and travel bans for director Ahn Joon-young, chief producer Kim Yong-bum, a producer with the surname Lee, and Starship Entertainment's vice president Kim Kang-hyo,[41] after they had attempted to destroy evidence.[42] By evening, Ahn and Kim Yong-bum were arrested.[43] During questioning, Ahn admitted to having manipulated the rankings for Produce 48 and Produce X 101.[44] Police also found that Ahn had been using services from adult entertainment establishments in Gangnam paid for by various talent agencies approximately 40 times beginning from the second half of 2018, estimating to ₩100 million.[44]
On May 29, 2020, director Ahn Joon-young and chief producer Kim Yong-bum have been sentenced to 2-year and 20 months of jail time respectively.[45] On November 18, 2020, The 1st Criminal Division of the Seoul High Court sentenced CJ ENM's general producer Kim Yong-beom, who was charged with obstruction and fraud, to 1 year and 8 months in prison. On the same day, the judiciary also directly disclosed the names of the trainees who were unjustly eliminated, which included Anzardi Timothee (61st), whose first voting results were manipulated, Kim Kookheon (21st) and Lee Jinwoo (22nd), who were eliminated due to the manipulation of the third voting, and Koo Jung-mo (13th), Lee Jinhyuk (14th), and Keum Donghyun (17th), who were supposed to be in the 6th to 8th places of the final rankings.[46]
