Starting in 1956, John Lennon and several of his friends played in a British band called the Quarrymen. Over the next few years, the members of the band changed, and by 1960, the band was called the Beatles. They did not have their first hit until 1962. In February 1963 their song, "Please Please Me", reached the number 1 position on the British charts. This was the first of a record 15 British number 1 singles. They first came to the United States in 1964. They were met at the airport by thousands of screaming American teenagers. The Beatles were so popular that they were attacked by screaming fans everywhere they went around the world. The effect they had on their fans was known as 'Beatlemania'. The Beatles made their first live American television appearance on The Ed Sullivan Show on 9 February 1964. About 74 million viewers — about half of the American population — watched the group perform on the show. Beatles songs soon filled the top 5 places on the American top 40 chart - a record that has never been matched.
