Exo (stylized as EXO; /ˌɛks ˈəʊ/ eks-oh; Korean: 엑소) is a South Korean-Chinese boy band produced by S.M. Entertainment. Formed in 2011 in Seoul, South Korea, Exo comprises twelve members separated into two subgroups, Exo-K and Exo-M, performing music inKorean and Mandarin, respectively. Their name was taken from exoplanet, a term referring to planets outside of the Solar System.
Exo made their official debut on April 8, 2012 with the release of their debut single, “Mama”. The single was a moderate success; Exo-M’s version topped mainland Chinese music charts after only one day of release, and Exo-K’s “Mama” music video reached to number seven on YouTube’s Global Chart. The group’s two albums, the 2012 debut EP Mama and the 2013 comeback studio album XOXO, were major commercial successes, selling over a million units in total worldwide. The lead singles off XOXO, “Wolf” and “Growl”, were K-pop hits, landing first place trophies on music shows from all three of Korea’s major free-to-air broadcast stations. The latter also peaked at number three on Billboard’s Korea K-Pop Hot 100 chart.
The group received numerous “newcomer” awards in 2012, and has since won over ten awards since their debut in April 2012.
