ABBA (often stylized as AᗺBA) was a Swedish pop/rock group formed in Stockholm in 1972, comprising Agnetha Fältskog, Benny Andersson, Björn Ulvaeus and Anni-Frid Lyngstad. ABBA is an acronym of the band member's first names. They became one of the most commercially successful acts in the history of pop music, topping the charts worldwide from 1972 to 1982. They are also known for winning the 1974 Eurovision Song Contest, giving Sweden its first victory in the history of the contest and being the most successful group ever to take part in the contest.
ABBA broke up in late 1982, due to relationship strains, but Agnetha has let out a rumour that ABBA might reunite in 2014.
