Abba are one of Sweden's biggest exports and the world's biggest pop act. With sales estimated at 400 million, as a group they are second only the Beatles. However, the pop music that will be remembered for generations to come grew out of a very different sound. Abba entered the Eurovision heats. They succeeded and performed the song Waterloo in the 1974 contest. The band entered superstar status with the 1976 release of their first greatest hits. The token new song on the record was Fernando. It remains Abba's biggest-selling single to date, with sales of 10 million copies. The late 1970s was a period of unstoppable success for Abba.
