The Beatles were an English musical group from Liverpool whose members were John Lennon, Paul McCartney, George Harrison, and Ringo Starr. They are one of the most commercially successful and critically acclaimed bands in the history of popular music.[2] The Beatles are the best-selling musical act of all time in the United States of America, according to the Recording Industry Association of America, which certified them as the highest selling band of all time based on American sales of singles and albums.[3] In the United Kingdom, The Beatles released more than 40 different singles, albums, and EPs that reached number one. This commercial success was repeated in many other countries: their record company, EMI, estimated that by 1985 they had sold over one billion discs and tapes worldwide.[4] In 2004, Rolling Stone magazine ranked The Beatles #1 on its list of 100 Greatest Artists of All Time.[5] According to that same magazine, their innovative music and cultural impact helped define the 1960s,[2] and their influence on pop culture is still evident today. The Beatles led the mid-1960s musical 'British Invasion' into the United States. Although their initial musical style was rooted in 1950s rock and roll and homegrown skiffle, the group explored genres ranging from Tin Pan Alley to psychedelic rock. Their clothes, styles, and statements made them trend-setters, while their growing social awareness saw their influence extend into the social and cultural revolutions of the 1960s.
