ABBA (Swedish pronunciation: [²abːa]) are a Swedish pop group, formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson, and Anni-Frid Lyngstad. The group's name derives from the first letter in each of the first names of its members. They became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1974 to 1982. ABBA won the Eurovision Song Contest 1974 at The Dome in Brighton, UK, giving Sweden its first triumph in the contest. They are the most successful group to have taken part in the competition.
ABBA are estimated to have sold 140 to over 500 million records, making them one of the best-selling music artists of all time. They are also the best-selling band from continental Europe and from outside the English-speaking world. ABBA is the first group from a non-English-speaking country to achieve consistent success in the charts of English-speaking countries, including the United Kingdom, Ireland, Canada, Australia, New Zealand, South Africa, and the United States. They have a joint record eight consecutive number-one albums in the UK. The group also enjoyed significant success in Latin America, and recorded a collection of their hit songs in Spanish.
During the band's active years, the band was composed of two couples: Fältskog and Ulvaeus, and Lyngstad and Andersson. With the increase of their popularity, their personal lives suffered which eventually resulted in the collapse of both marriages. The relationship changes were reflected in the group's music, with later compositions featuring more introspective and dark lyrics.
After ABBA disbanded in December 1982, Andersson and Ulvaeus achieved success writing music for the stage, while Lyngstad and Fältskog pursued solo careers with mixed success. ABBA's music declined in popularity until the purchase of ABBA's catalogue and record company Polar by Polygram in 1989 enabled the groundwork to be laid for an international re-issue of all their original material and a new Greatest Hits (ABBA Gold) collection in September 1992, which became a worldwide bestseller. Several films, notably Muriel's Wedding (1994) and The Adventures of Priscilla, Queen of the Desert (1994), further revived interest in the group and spawned several tribute bands. In 1999, ABBA's music was adapted into the successful musical Mamma Mia! that toured worldwide. A film of the same name, released in 2008, became the highest-grossing film in the United Kingdom that year. A sequel is due to be released in 2018.
ABBA were honoured at the 50th anniversary celebration of the Eurovision Song Contest in 2005, when their hit "Waterloo" was chosen as the best song in the competition's history. The group was inducted into the Rock and Roll Hall of Fame in 2010. In 2015, their song "Dancing Queen" was inducted into the Recording Academy's Grammy Hall of Fame.
On April 27, 2018, it was announced that the band had recorded two new songs after 35 years of being inactive, the first of which – "I Still Have Faith in You" – will be released in December 2018.
