===Beatlemania and Early Albums (1963–1965)===

The Beatles became a cultural phenomenon of unprecedented scale in Britain in 1963, with the press coining the term '''Beatlemania''' to describe the hysteria surrounding the group. Their arrival in the United States in February 1964 — broadcast live on ''The Ed Sullivan Show'' to an estimated audience of 73 million viewers — launched a British Invasion of American popular music and popular culture that fundamentally altered the landscape of rock and roll.

Early albums including ''Please Please Me'' (1963), ''With the Beatles'' (1963), ''A Hard Day's Night'' (1964), and ''Help!'' (1965) combined energetic original songwriting with rock and roll and Motown influences. The Lennon–McCartney songwriting partnership, though increasingly divergent in sensibility, produced an extraordinary run of singles and album tracks that dominated charts on both sides of the Atlantic.
