The Beatles, formed in Liverpool in 1960, comprised John Lennon, Paul McCartney, George Harrison, and Ringo Starr and are widely regarded as the most influential band in popular music, pioneering new sounds and helping define the 1960s counterculture. After evolving from Lennon's earlier group the Quarrymen, they were shaped by manager Brian Epstein and producer George Martin, achieving their first hit "Love Me Do" in 1962, sparking "Beatlemania," and becoming international stars in 1964, leading the British Invasion of the US and making their film debut with A Hard Day's Night. Retiring from live performances in 1966, they produced increasingly sophisticated albums like Rubber Soul (1965), Revolver (1966), Sgt. Pepper's Lonely Hearts Club Band (1967), the White Album (1968), and Abbey Road (1969), which heralded the album era and advanced electronic music, album art, and music videos. They founded Apple Corps in 1968, but broke up in 1970; all members enjoyed solo success, though Lennon was murdered in 1980 and Harrison died of lung cancer in 2001, while McCartney and Starr remain active. As the best-selling music act of all time with over 600 million units sold, they hold records for the most number-one singles (20) and albums (19) on the US Billboard charts, and have won nine Grammys, an Academy Award, and were inducted into the Rock and Roll Hall of Fame in 1988. Their legacy is further cemented by topping Rolling Stone's greatest artists lists and being named among Time's 100 most important people of the 20th century.
