From 1960, the Beatles built their reputation playing clubs in Liverpool and Hamburg over a three-year period. Manager Brian Epstein moulded them into a professional act and producer George Martin enhanced their musical potential. They gained popularity in the United Kingdom after their first hit, "Love Me Do", in late 1962. They acquired the nickname "the Fab Four" as Beatlemania grew in Britain over the following year, and by early 1964 they had become international stars, leading the "British Invasion" of the United States pop market. From 1965 onwards, the Beatles produced what many critics consider their finest material, including the innovative and widely influential albums Rubber Soul (1965), Revolver (1966), Sgt. Pepper's Lonely Hearts Club Band (1967), The Beatles (commonly known as the White Album, 1968) and Abbey Road (1969). After their break-up in 1970, they each enjoyed successful musical careers. Lennon was shot and killed in December 1980, and Harrison died of lung cancer in November 2001. McCartney and Starr, the surviving members, remain musically active.
According to the RIAA, the Beatles are the best-selling music artist in the United States, with 177 million certified units. They have had more number-one albums on the British charts and sold more singles in the UK than any other
