Drama Korea

T-ara (pron.: /tiˈɑːrə/; Korean: 티아라, Japanese: ティアラ, often stylized as T-ARA or T♔ARA) is a South Korean girl group that debuted in 2009 under Core Contents Media. Before their debut, there was a high level of interest in the group; they were called the "Super Rookies" and had been training for three years prior.
Originally a five-member group composed of Jiae, Jiwon, Eunjung, Hyomin, and Jiyeon, they released their first song "Joheun Saram" (좋은 사람, "Good Person") for the soundtrack of the Korean drama Cinderella Man in April 2009. After Jiae and Jiwon withdrew from the group in June, T-ara debuted as a six-member group with the addition of Boram, Soyeon, and Qri in July 2009.
Their debut studio album Absolute First Album was released in December 2009 and spawned several hit singles including "Geojitmal", "TTL (Time to Love)", "TTL Listen 2", "Bo Peep Bo Peep", "Cheoeum Cheoreom" and "Neo Ttaemune Michyeo". The album was followed by the group's first extended play, Temptastic (2010), which included the top-five singles "Wae Ireoni" and "Yayaya". John Travolta Wannabe (2011) produced "Roly-Poly", the Gaon chart's number one single of the year, which earned the group several awards and nominations as well. In less than six months, the group released their third extended play Black Eyes (2011), which spawned three number one singles: "Cry Cry", "Uri Saranghaetjanha" and "Lovey-Dovey". The lead single, "Cry Cry", became the group's first number one on the Billboard Korea K-Pop Hot 100.
In 2011, T-ara signed a $4.3 million contract with the company J-ROCK for their Japanese debut, the highest out of all the girl groups debuting in Japan. Their major record label is EMI Music Japan while their management and promotional marketing takes place under J-ROCK. The group's first single was a remake of their 2009 hit "Bo Peep Bo Peep". It ranked at number one on the Oricon weekly charts with 49,712 copies sold, the first time a debuting Korean girl group has done so in the charts' history. T-ara released their debut Japanese studio album Jewelry Box in 2012, which peaked at number two on the Oricon charts.
The group has added three members to their lineup since debut: Hwayoung in 2010, Areum in June 2012, and Dani was announced to be joining the group in December 2012 (although she has yet to join the group). Hwayoung later departed the group in July 2012. T-ara uses a rotating leader system in which a different member of the group is elected as leader each year, in order to give both the group and the individual members the opportunity to grow in a new direction.

Girls' Generation is a South Korean girl group formed by S. M. Entertainment in 2007.The nine member group consists of Taeyeon, Jessica, Sunny, Tiffany, Hyoyeon, Yuri, Sooyoung, Yoona and Seohyun.
The group gained attention at the beginning of their career with songs such as "Into the New World" and "Kissing You" but it was not until 2009 when they gained significant popularity with their hit single "Gee", which would be named as South Korea's "Song of the Decade". The group solidified their place in the Korean music industry with follow-up singles "Tell Me Your Wish", "Run Devil Run", and "Oh!" from late 2009 to early 2010. In 2011, after a series of activities in Japan, the group returned to the Korean music scene with "The Boys", which was released in three languages: Korean, Japanese, and for the first time, English. In 2010 alone, the group sold more than 11,730,000 albums and singles collectively. The group's immense popularity in their native South Korea has earned them titles "The Nation's Singers" and "The Nation's Girl Group". The Sisa Journal named the group as the most influential entertainers for the years 2011 and 2012, making them the first female idol group in history to make the list. They have also been listed as #1 on the Top Female Singer's list for 4 consecutive years in a row (sans 2nd half of 2011 at #2) on the Leespiar Popularity Survey in Korea. Asia Today placed the group at forty-four on the 50 Korean Power Leaders list in 2011. Forbes also revealed the group were most powerful entertainers in South Korea for the year of 2011.
The group began a foray into the Japanese music scene in late 2010 under Nayutawave Records, with Japanese remakes of their 2009 Korean hits "Genie" and "Gee". The group's debut Japanese album, Girls' Generation, released in June 2011, is currently the highest selling album in Japan by a Korean group in Oricon history. It was certified "Million" by the Recording Industry Association of Japan, which made them the second Korean artist to earn such an achievement in Japan since label mate BoA's "Best of Soul" in 2005. The group followed up their success in Japan with their second album, Girls' Generation II ~Girls & Peace~.
They have expanded their reach in the Korean industry through their first sub-unit, Girls' Generation-TTS (known simply as "TaeTiSeo"), composed of members Taeyeon, Tiffany, and Seohyun. The subgroup's debut EP, Twinkle, peaked at #126 on the Billboard 200, becoming the highest charting K-Pop album on the chart thus far.
