ABBA was a Swedish pop group formed in Stockholm in 1972. The name is an acronym of the first letters of the band members' first names and is sometimes stylized as the registered trademark ᗅᗺᗷᗅ. The band became one of the most commercially successful acts in the history of popular music, topping the charts worldwide from 1975 to 1982. It also won the Eurovision Song Contest 1974, giving Sweden its first triumph in the history of the contest and being the most successful group ever to take part in the competition.
ABBA has sold over 380 million albums and singles worldwide, which makes it one of the best-selling music groups of all time. ABBA was the first 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, and South Africa. The group also enjoyed significant success in Latin American markets, and recorded a collection of their hit songs in Spanish.
