ABBA was a Swedish pop group formed in Stockholm in 1972, comprising Agnetha Fältskog, Benny Andersson, Björn Ulvaeus and Anni-Frid Lyngstad. They became one of the most commercially successful acts in the history of pop music, topping the charts worldwide from 1972 to 1982. ABBA has sold over 370 million records worldwide and still sell millions of records a year, which makes them one of the best-selling music artists, and the second best selling music group in history, only behind The Beatles . ABBA was the first pop group to come from a non-English-speaking country that enjoyed consistent success in the charts of English-speaking countries, including the UK, Ireland, the U.S., Canada, Australia, New Zealand, South Africa and the Philippines. The group also enjoyed significant success in Latin American markets (particularly Mexico, Brazil,Chile, Peru, Colombia and Argentina), and recorded a collection of their hit songs in Spanish.
During the band's active years, Fältskog and Ulvaeus were a married couple, as were Lyngstad and Andersson–although both couples later divorced.
