In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. Thanks to cooperation with Western Union the Associated Press at the end of the XIX century took almost monopolistic position in the U.S. market news. In 1856, in 7 years after the foundation of New York State Printing Telegraph Company, the company changed its name to Western Union Telegraph Company.
