2NE1 (Korean: 투애니원; two-eh-nee-one) is a four-member South Korean hip-hop/pop girl group formed by YG Entertainment in 2009. The band consists of four members: CL, Minzy, Dara, and Bom . The name 2NE1 combines the phrases "21st century" and "new evolution", and is pronounced "twenty-one" or "to anyone".
They first appeared in "Lollipop", a commercial campaign with Big Bang for LG Electronics, and their debut single "Fire" was released on May 6, 2009. Since then, the group has released two extended plays, 2NE1 and 2NE1 2nd Mini Album, and one studio album, To Anyone. Their first EP, 2NE1 spawned the number-one single "I Don't Care", which won them the "Song of the Year" award from the Mnet Asian Music Awards. Their follow-up singles, such as "Go Away", "Lonely" and "I Am The Best" were similarly successful.
2NE1 officially debuted in Japan in September 2011 with a mini album titled NOLZA, which contained re-made versions of their Korean songs. Since then, the group has released one mini-album NOLZA and one physical single "Go Away".
Representing South Korea, 2NE1 emerged as the winner in the voting competition for "Best New Band", which was an international competition held by MTV Iggy. The band was officially crowned the winner on November 10, 2011.
Fans of 2NE1 are called Blackjacks, which is a reference to the card game Blackjack, also known as Twenty-one.
