American chart success began after disc jockey Carroll James obtained a copy of the British single "I Want to Hold Your Hand" in mid-December and began playing it on AM radio station WWDC in Washington, DC. Listeners repeatedly phoned in to request a replay of the song, while local record shops were flooded with requests for a record that they did not have in stock. James sent the record to other disc jockeys around the country, sparking similar reaction. On 26 December, Capitol released the record three weeks ahead of schedule. It sold a million copies and became a number-one hit in the US by mid-January. Epstein arranged for a $40,000 American marketing campaign, a deal Capitol accepted due to Ed Sullivan's agreement to headline the Beatles on "The Ed Sullivan Show".
