AOA (group)

AOA (Korean: 에이오에이; an acronym for Ace of Angels) is a South Korean girl group formed by FNC Entertainment. The original 2012 eight-member line-up included: Choa, Jimin, Yuna, Youkyung, Hyejeong, Mina, Seolhyun, and Dohwa. Youkyung left the group in 2016, while Choa left in 2017 due to mental health reasons, followed by Mina in 2019 to pursue her acting career, and Jimin in 2020 due to bullying allegations. Yuna left in 2021 due to her contract expiration. It was later announced in October 2022, that Seolhyun would also be leaving the company. The group currently consists of Hyejeong and Dohwa(Chanmi).

AOA began their career simultaneously promoting as a dance group and band, and officially debuted in July 2012 with the release of the single album Angel's Story. In early 2013, the band unit AOA Black released their official single titled "MOYA" to moderate success. They released their first EP in June 2014, and that year they also debuted in Japan under Universal Music Japan. The group found nationwide success in 2014 after a series of hit songs that established them as one of the leading girl groups of their era. "Heart Attack" debuted at the top of several charts after its release, became one of the most downloaded songs of 2015, and became one of the longest charting singles on Melon's top 100 chart.

Following a series of consistent success, AOA debuted a second promotional unit, AOA Cream, in 2016. The group would later release their first Korean language studio album in January 2017, and a few months later, held their first headlining Korean concert "Ace Of Angels" at Olympic Hall in Seoul. Among the groups' biggest hits are "Miniskirt", "Short Hair", "Like a Cat", "Heart Attack", "Give Me the Love", "Good Luck", "Excuse Me", and "Bingle Bangle". The group has been inactive since 2019, following a series of scandals within the group's lineup.
