The Beatles were an English rock band formed in Liverpool in 1960. With a line-up comprising John Lennon, Paul McCartney, George Harrison and Ringo Starr, they are regarded as the most influential band of all time. The group were integral to the development of 1960s counterculture and popular music's recognition as an art form. Rooted in skiffle, beat and 1950s rock and roll, their sound incorporated elements of classical music and traditional pop in innovative ways; the band later explored music styles ranging from ballads and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the group revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.Led by primary songwriters Lennon and McCartney, the Beatles built their reputation playing clubs in Liverpool and Hamburg over three years from 1960, initially with Stuart Sutcliffe playing bass. The core trio of Lennon, McCartney and Harrison, together since 1958, went through a succession of drummers, including Pete Best, before asking Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act and producer George Martin guided and developed their recordings, greatly expanding their domestic success after their first hit, "Love Me Do", in late 1962. As their popularity grew into the intense fan frenzy dubbed "Beatlemania", the band acquired the nickname "the Fab Four", with Epstein, Martin and other members of the band's entourage sometimes given the informal title of "fifth Beatle".
By early 1964, the Beatles were international stars, leading the "British Invasion" of the United States pop market and breaking numerous sales records. They soon made their film debut with A Hard Day's Night (1964). From 1965 onwards, they produced increasingly innovative recordings, including the albums Rubber Soul (1965), Revolver (1966) and Sgt. Pepper's Lonely Hearts Club Band (1967), and enjoyed further commercial success with The Beatles (also known as "the White Album", 1968) and Abbey Road (1969). In 1968, they founded Apple Corps, a multi-armed multimedia corporation that continues to oversee projects related to the band's legacy. After the group's break-up in 1970, all four members enjoyed success as solo artists. Lennon was shot and killed in December 1980, and Harrison died of lung cancer in November 2001. McCartney and Starr remain musically active.
The Beatles are the best-selling music act of all time, with certified sales of over 183 million units in the US and estimated sales of 600 million units worldwide. They hold the record for most number-one albums on the UK Albums Chart, most number-one hits on the Billboard Hot 100 chart, and most singles sold in the UK. The group were inducted into the Rock and Roll Hall of Fame in 1988, and all four main members were inducted individually between 1994 and 2015. In 2008, the group topped Billboard's list of the all-time most successful artists on the Billboard Hot 100. The band received seven Grammy Awards, four Brit Awards, an Academy Award (for Best Original Song Score for the 1970 film Let It Be) and fifteen Ivor Novello Awards. Time magazine named them among the 20th century's 100 most important people.
