2NE1's first extended play 2NE1 (2009) was preceded by two singles.
The first one, "Lollipop", was recorded with label mate Big Bang and released on March 27, 2009 to promote the LG Cyon phone.
Though a music video was filmed, "Lollipop" was not promoted due to its product advertisement affiliation, which caused issues with the network chart eligibility.
The second single, "Fire", written and produced by 1TYM's Teddy Park, was released that May and contained elements of hip-hop and reggae.
Its music video had two versions — a "space" version and a "street" version.
Within the first 24 hours of release, the videos each received over one million views.
Both the song "Fire" and the group became popular online search terms.
The final single, "I Don't Care", was released simultaneously alongside their first eponymous EP in July.
Promotional activities quickly followed to demonstrate a softer, more feminine image of the group to contrast the edgier image previously portrayed in "Fire". "
I Don't Care" became the most downloaded song of that month, later winning Song of the Year at the Mnet Asian Music Awards.

Although group members recorded and released their own solo materials in August, they performed a reggae version of "I Don't Care" on Inkigayo in September.
Due to the remix's popularity, it was released to digital outlets on September 3 as their next digital single.
Buoyed by the success of their singles, sales of 2NE1 totaled 100,000 copies by the end of the year.
2NE1 later performed at the 6th Asia Song Festival, representing Korea alongside three other groups and later winning the Asian Newcomer's award.

In 2010, 2NE1 unexpectedly released "Try to Follow Me" in February through various digital outlets without any prior announcement or promotion to support the Samsung's Corby Folder.
The song peaked at number one on the Gaon Digital Chart.
That summer, 2NE1 traveled to Los Angeles and London to record English songs for an American debut album with The Black Eyed Peas's member and music producer will.i.am.
The group recorded a total of 10 songs in their initial sessions.
The quartet's first full-length album, To Anyone (2010), was released on September 9, and debuted at number 7 on the Billboard World Album Chart.
Prior to the release of the album, it had already received 120,000 preorders.
Containing a total of 12 tracks, four singles were released: the top five hits "Clap Your Hands", "Can't Nobody", "It Hurts (Slow)" and the chart-topping "Go Away".
A fifth song "Don't Stop the Music" was recorded as a "special gift for Thai fans" and was also used in conjunction with the group's Yamaha Fiore endorsement.
At the 2010 Mnet Asian Music Awards, 2NE1 took home the most accolades: "Artist of the Year", "Best Music Video" for "Can't Nobody", "Best Female Group", and "Album of the Year" award.
