when were the beatles popular

The Beatles were popular primarily from 1963 to 1966 during the height of "Beatlemania." Their popularity began growing in the United Kingdom in late 1963 with hits like "Please Please Me," "From Me to You," and "She Loves You." By 1964, they had become international stars in the United States, famously appearing on The Ed Sullivan Show to an audience of about 73 million people. Their intense fan frenzy and cultural impact made them dominant figures in popular music through the mid-1960s, especially from 1963 to 1965 during which they revolutionized rock and pop music. Their music continued to influence popular culture and counterculture throughout the 1960s.
