Learn More About Groups Formed Through Mnet’s Produce 101

Are you one of the people who fancy survival shows? If you are, you might be familiar with one of the most popular survival shows in South Korea, the Produce series! So far, there have been four seasons of the Produce Series: Produce 101 season 1 and season 2, Produce 48, and Produce X 101. Through these series, two girl groups and two boy groups in which the members were picked by the public were formed groups with their own uniqueness. Are you curious about the groups that were formed by these survival shows? Today, Channel-Korea will explain everything about the groups that were formed through the Produce series. So, stay tuned!



Ideal of Idol, or better known as I.O.I, is the first group that was formed through the survival show Produce 101, and it consisted of eleven girls from various entertainment companies: Jeon So-mi from JYP Entertainment, Kim Se-jeong and Kang Mi-na from Jellyfish Entertainment, Lim Na-young and Zhou Jieqiong from Pledis Entertainment, Kim Do-yeon and Choi Yoo-jung from Fantagio, Kim Chung-ha from MNH Entertainment, Yoo Yeon-jung from Starship Entertainment, Kim So-hye from Redline Entertainment, and Jung Chae-yeon from MBK Entertainment.

Being the first group to be formed through Produce 101, I.O.I received a lot of interest even prior to their debut. This is because when they were still competing as participants in Produce 101, a few of the members of I.O.I had appeared in public through another show. For example, Jeon So-mi had appeared on another survival show titled Sixteen previously, Kim Se-jeong had appeared on K-pop Star 2, Choi Yoo-jung had appeared in the web drama To Be Continued. Not only that, but there is also a member who is active in another group, which is Jung Chae-yeon who is active as a member of DIA. Meanwhile, the other members also piqued the public’s interest as they made a strong impression, such as Kim Chung-ha with her powerful dancing, or Kim Na-young who was known for her stone face.

After surviving in the show, they eventually debuted with their first EP titled Chrysalis, accompanied with a music video for their title track “Dream Girls.” However, as much as they piqued the public’s interests, there were also many controversies that surrounded them during their debut.

The first one is their title track “Dream Girls,” which was revealed to be blind picked by the girls through their reality program titled Standby I.O.I, but later it was revealed that the composer of the title track is Eru who’s an artist under YMC Entertainment. The second one is the music video of “Dream Girls.” In the music video, Jung Chae-yeon is the one who stands in the center of the chorus, which was not well received by Jeon So-mi’s fans and the viewers of Produce 101. This is because it was told that whoever wins the first place will become the center and Jeon So-mi was voted as the first place, not Jung Chae-yeon. This problem also sparked unfairness to other members who ranked higher than Jung Chae-yeon.

There were also controversies surrounding I.O.I’s main vocalists, Yoo Yeon-jung and Kim Se-jeong, because they didn’t receive enough parts in the song, which made the fans upset. Lastly, there were also fans who wanted Kim So-hye to drop out from I.O.I and get replaced by either Park So-yeon or Han Hye-ri. This controversy might have risen because Kim So-hye was first placed in the lowest class and she seemed not skilled quite enough to join the group, which made some fans think that she’s not qualified to join the final line-up.

IOI Whatta Man

Another controversy rose up when the group decided to release a song under a unit, while in reality, it’s just the members of I.O.I without Jung Chae-yeon, Kim Se-jeong, Kang Mi-na, and Yoo Yeon-jung who returned to their respective company to focus on another activity. When first announced that I.O.I will make a unit, the fans expected that the subunit was purposefully formed to promote certain concepts or traits, but it didn’t turn out like that. Of course, this made the fans extremely disappointed as they thought that rather than a subunit, the group feels like an incomplete unit that was created out of necessity.

The time passed and I.O.I made their comeback with another EP titled Miss Me? with “Very Very Very” as the title track. In this era, I.O.I received their first music program trophy as a whole group with the track on Show Champion. Overall, the group’s concept was cute and bubbly, except for the subunit that took a girl crush concept for their song.

The group was disbanded on January 31st, 2017, and they released a final track titled “Downpour” prior to their official disbandment. They also held their final concert Time Slip – I.O.I  for three days, from January 20th to January 22nd, 2017.


Wanna One

WANNA ONE was a boy group that was formed through the second season of Produce 101. Similar to I.O.I, the group consisted of eleven members from various companies: Kang Daniel, Park Ji-hoon, Lee Dae-hwi, Kim Jae-hwan, Ong Seong-woo, Park Woo-jin, Lai Kuan-lin, Yoon Ji-sung, Hwang Min-hyun, Bae Jin-young, and Ha Sung-woon. Just like a few members of I.O.I, some members from WANNA ONE had already been active in the entertainment industry when they participated as a contestant of Produce 101: Park Ji-hoon was a child actor, Hwang Min-hyun had already made his debut as a member of NU’EST, Kim Jae-hwan participated in the second season of Korea’s Got Talent, and Ha Sung-woon previously debuted as a member of Hotshot.

WANNA ONE debuted with their first EP titled 1×1=1 (To Be One) with “Energetic” as their title track, which was composed by Hui of Pentagon and FlowBlow. Two music videos were released for their debut, which were “Energetic” and “Burn It Up.” Later, they released their repackaged album, 1-1=0 (Nothing Without You) with the title track “Beautiful.” With the sales of their first album and its repackaged edition combined, WANNA ONE became the third group to sell a million copies of their debut album, and the first since Seo Taiji and Boys did. The group disbanded on December 31st, 2018, and just like I.O.I, they held a final concert Therefore which was held across four days.


During their active days, WANNA ONE had also stirred up some controversies. Prior to the release of their second mini-album 0+1=1 (I Promise You), WANNA ONE appeared on Mnet’s Star Live. Without realizing, their live broadcast started earlier than scheduled, and while they were waiting, the members had made some remarks that shocked the fans. After this accident, criticism poured out against them and the fans were highly disappointed as well as hurt by their shocking words, while many netizens also bashed them for their lack of modesty and manners. In response to this, WANNA ONE and their company, YMC Entertainment, as well as Mnet, officially apologized for the accident. Meanwhile, there were also controversies that centered on one of the members, Yoon Ji-sung. He had been caught in a controversy related to his attitude and attire for an event, and not much later, he was caught in a controversy related to his education background and military enlistment. Despite getting caught in many controversies, they still received a lot of love from the fans until the end of their contract and received many awards for their performances.



IZ*ONE is the third group that was formed through Produce 101. Quite different from the two previous seasons, this time, the Produce 101 franchise collaborated with the Japanese idol AKB48 group, which made the show titled as Produce 48. The group consisted of twelve members: Jang Won-young, Miyawaki Sakura, Jo Yu-ri, Choi Ye-na, An Yu-jin, Yabuki Nako, Kwon Eun-bi, Kang Hye-won, Honda Hitomi, Kim Chae-won, Kim Min-ju, and Lee Chae-yeon. The group’s name IZ*ONE, was suggested by netizens and chosen by CJ ENM. ‘IZ’ represented the number 12, while ‘ONE’ indicates that the members are one as a group and the asterisk (*) between symbolizes a sign of the zodiac.

Just like I.O.I and WANNA ONE, a few members of IZ*ONE had already been active in the entertainment industry. Honda Hitomi had debuted with AKB48, Miyawaki Sakura had appeared in a Shiki Theatre Company musical production of The Lion King and joined HKT48, and Yabuki Nako had appeared in various Japanese television dramas, movies, as well as commercials. Meanwhile, Kwon Eun-bi previously debuted with Ye-A but left the group, Lee Chae-yeon previously competed in JYP’s survival show Sixteen, Jo Yu-ri was a contestant of Mnet’s Idol School, while Kim Min-ju and An Yu-jin both had appeared as actresses prior to Produce 48.

IZ*ONE had their official debut in Korea by releasing their first EP Color*Iz, with “La Vie en Rose” as their title track. They also held a debut showcase concert titled Color*Iz Show-Con, in which the tickets were sold out within a minute of going on sale. They also received their first music program win a week later on M! Countdown, ten days after their official debut and broke the record for the fastest girl group to receive a music program win at the time. Meanwhile, IZ*ONE held their Japanese debut show-con in Tokyo Dome City Hall to promote their first Japanese single titled “Suki to Iwasetai.” Five days after the event, the group released the music video for the song and the views on YouTube surpassed 5 million within a week. IZ*ONE held their first solo concert, Eyes On Me, at the Jamsil Indoor Stadium in Seoul from June 7th to June 9th, 2019. Meanwhile, it was reported that they will release their third Japanese single titled “Vampire” on September 25th, 2019.


While promoting, IZ*ONE too has faced some controversies during their active days. Even at the time of their debut, they already faced a controversy in which there was a national petition on the Blue House website to ban them from appearing on KBS, the Korean public television channel, and its music show Music Bank. This is because AKB48 is a well-known group that actively supports Japanese right-wing and its activities, while the issues regarding Japanese right-wing are a sensitive topic in Korea due to the history between the two countries. IZ*ONE were also caught up in another controversy where they have never sung live in any of their performances from their debut stage until the year-end award ceremonies.

Meanwhile, one of the members of IZ*ONE, Jang Won-young was also involved in a few scandals. She has caused a lot of controversies when becoming the winner in Produce 48 and also received criticism for lack of respect toward her senior. This happened because she imitated Lee Dae-hwi from WANNA ONE in Nayana, but many people thought that she over-mimicked to the point that she made Lee Dae-hwi upset while he was sitting to see the performance. She also received a lot of criticism regarding her attitude toward An Yu-jin during the Color*Iz album photoshoot. An Yu-jin, who wore a strip and appeared different from the other members, jokingly said that she felt like a leader. When everyone laughed at her joking behavior, only Jang Won-young had a different attitude in which she looked at the older one with sarcasm.
