Wonder Girls (원더걸스, ワンダーガールズ) was a Korean pop girl group created by JYP Entertainment. They debuted in 2007 with rapper and sub vocalist Hyun A whom later left the group on July 20, 2007 citing illness. Yubin later took her place and the group became known for their songs "Tell Me", "So Hot", and "Nobody". In 2009 Wonder Girls announced their expansion in the United States and China, and the group was the opening act for the Jonas Brothers North American leg for their 2009 World Tour. However on January 22, 2009 it was announced that original member Sunmi would postpone her music career to pursue an academic career; Hye Rim replaced her. On November 26, 2012, JYP Entertainment announced that Sun Ye would be getting married on January 26, 2013 and members will focus on individual activities after the marriage for the time being. Due to Sun Ye's pregnancy, rumors have surfaced that she is leaving the group and Wonder Girls have broken up. In December 2013, So Hee left JYP Entertainment and will focus on acting. In June 2015, JYP confirmed the group would return after July as a four member group, Sunmi rejoining while Sun Ye would not participate. On July 20, JYP officially announced Sun Ye and So Hee's departure from the group. On January 26, 2017, JYP announced that Sunmi and Ye Eun didn't renew their contract with the agency and the group would be disbanding after a final single on February 10, the same day as the 10th anniversary since their debut.
III. 2001-2007: Pre-Debut Search and Debut Era
On July 1, 2001 Park Jin Young, the founder and CEO of JYP Entertainment, held an open audition called the Talent & Live Voice Project 99% Competition in order to find talented young females that would be trained for his planned idea to create his first girl group. Wonder Girls, a documentary program filmed and aired on MTV Korea, revealed the name of Park Jin Young's girl group as the Wonder Girls on May 22, 2006. The program introduced the four members of the Wonder Girls which were Sun Ye, So Hee, Hyun A, and Sunmi. Ye Eun was later recruited as the fifth member of the group and not long after her addition, Wonder Girls official debut was held at Show! Music Core where they performed their hip-hop song "Irony" on February 10, 2007.
They held their first showcase at the “MTV Studio” on February 13, 2007. The group began their performance by performing a cover of "Don’t Cha" by the Pussycat Dolls, followed by "Irony" and "Mianhan Maeum ~tears~". Following their group performances, Wonder Girls showed off their individual talents with solo performances. Sun Ye sang “Stand Up for Love" by Destiny’s Child, Hyun A performed a solo dance, and Sunmi, Ye Eun, and So Hee sang a cover of Janet Jackson’s "Together Again". The showcase was broadcast live on MTV. Sequentially, their debut single "The Wonder Begins" was released and according to the South Korean music charts, the single sold 11,454 copies that year. After their debut, the Wonder Girls met a series of injuries. On June 25, 2007 So Hee tore a knee ligament due to falling off of a motorcycle while filming Tteugeoun Geosi Joha; she was precluded from group activities for one month. The four remaining members continued performing. Three performances Hyun A was missing and a clothing ad featuring Wonder Girls without her, on July 20, 2007 Hyun A announced her withdrawal from Wonder Girls due to Gastroenteritis and fainting spells.
IIII. 2007-2008: Tell Me Syndrome And Two Massive Hits
Yubin was appointed to be the replacement for Hyun A. She was to debut with another girl group under Good Entertainment; having received training for approximately two years. However, the company's financial situation worsened and the group's debut never came into fruition. Two teaser posters of So Hee were erected across Seoul to promote their debut album The Wonder Years.
The concept for the album was described as "80's retro", and "Tell Me" was announced as the group's lead single. Their debut performance for "Tell Me" was at Music Bank on September 7, 2007. However, on September 14, 2007 Wonder Girls were involved in a car accident. Their van rear-ended a taxi on their way back from a performance at Dong-eui University, and the accident resulted in the death of the taxi driver and minor injuries to the group. Due to the tragic outcome and emotional trauma the group experienced, "Tell Me" promotional activity was temporarily suspended for two weeks. Wonder Girls continued "Tell Me" promotional activity on September 27, 2007 at Inkigayo. The choreography for the song was easy and widely mimicked with numerous videos of fan performances circulating the internet on South Korean video sharing sites such as Daum and YouTube. The popularity of the dance became known as "Tell Me Fever" or "Tell Me Syndrome", and earned Wonder Girls the title of "Korea's Little Sisters". "Tell Me" won the #1 "Mutizen" awards on Inkigayo three times, five times on Music Bank, and once on Music Core and M! Countdown. The song stayed at the top of various online music charts for 7 consecutive weeks, and the group won the 2007 Music Bank "Song of the Year" award, the "Anycall Popularity" and "Digital Bonsang" awards at the 2007 Golden Disk Awards, and "Best New Female Group" for "Irony" at the 2007 Mnet Asian Music Awards. Wonder Girls continued to promote their debut album using "Ebabo" as their second single; on December 6, 2007 the debut performance for “Ebabo” was at M! Countdown.
Their second single "So Hot" was released June 3rd, 2008 and it was another hit for the group. In mid 2008, they performed on Music Core, performing "So Hot" and "This Time". Due to a vocal cord injury, Yubin temporarily lip-synched her parts under doctor's orders. After a very short break, they made a comeback with their first mini-album The Wonder Years - Trilogy. They performed the song "Nobody" the following weekend on Music Core, Music Bank and Inkigayo. The song quickly went to No. 1 on Music Bank, staying there for four consecutive weeks, and also won Cyworld's Song of the Month award in September and October 2008. Just like "Tell Me", "Nobody" also sparked a dance craze. At the 2008 Mnet KM Music Festival Awards, the Wonder Girls received three awards: the "Song of the Year" award, "Best Music Video" for "Nobody" and "Best Female Group". They also won an award at the 2008 Golden Disk Awards a month later for high digital sales. At the 18th Seoul Music Awards, the Wonder Girls won the Daesang award ("Artist of the Year"), the highest award offered, for "Nobody", and two other awards. They were also selected as a top girl group by Virgin Media.
