On 3 January 1964, "The Jack Paar Program" ran Beatles concert footage licensed from the BBC "as a joke" to an audience of 30 million viewers. On 7 February, an estimated 4,000 Beatles fans were present as Pan Am Flight 101 left Heathrow Airport. Among the passengers were the Beatles on their first trip to the US as a band, along with Phil Spector and an entourage of photographers and journalists. On arrival at New York's newly renamed John F. Kennedy International Airport, they were greeted by a crowd of 4,000 Beatles fans and 200 journalists. A few people in the crowd were injured, and the airport had not previously experienced such a large crowd. The band held a press conference where they met disc jockey Murray the K, then they were put into four limousines (one per Beatle) and driven to New York City. On the way, McCartney turned on a radio and listened to a running commentary: "They have just left the airport and are coming to New York City." When they reached the Plaza Hotel, they were besieged by fans and reporters. Author André Millard, writing in his book "Beatlemania: Technology, Business, and Teen Culture in Cold War America", says that it was this constant fan presence – outside the band's hotels, UK residences, and recording studios – that gave Beatlemania an "extra dimension that lifted it above all other incidents of fan worship".
