They formed in the late 1950s and gained recognition in Britain in the early 1960s through frequent performances in clubs. Their popularity skyrocketed internationally following the success of songs like "She Loves You" in 1963. Their arrival in the United States in the 1960s sparked unprecedented fan frenzy known as "Beatlemania".
