North America United States and Canada A 1 (900) telephone number, in the North American Numbering Plan, has the form 1 (900) ###-####, and is often called a 900 number or a 1 900 number ("one-nine-hundred"). Area code 900 went into service January 1, 1971, but the first known to have been used in the United States for the "Ask President Carter" program in March 1977, for incoming calls to a nationwide talk radio broadcast featuring the newly elected President Jimmy Carter, hosted by anchorman Walter Cronkite. At that time, the intent for area code 900 was as a choke exchange—a code that blocked large numbers of simultaneous callers from jamming up the long-distance network. Numbers with the 900 area code were those which were expected to have a huge number of potential callers, and the 900 area code was screened at the local level to allow only a certain number of the callers in each area to access the nationwide long-distance network for reaching the destination number. Also, the early incarnation of 900 was not billed at premium-rate charges, but rather at regular long-distance charges based on the time of day and day of week that the call was placed. The number used for the radio program was one that was specially arranged by AT&T Corporation, CBS Radio, and the White House, to be free to the calling party. However, by 1980, the 900 area code was completely restructured by AT&T to be the premium-rate special area code which it remains today. At that time, many evening news agencies conducted "pulse polls" for $0.50 per call charges and displayed results on television. One early use was by Saturday Night Live producers for the sketch "Larry the Lobster", featuring Eddie Murphy. The comedy sketch drew nearly 500,000 calls. AT&T and the producers of SNL split the profits of nearly $250,000. Earlier, 976 numbers used 976 as
