In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. In 1877, starting from September, New York City residents began to have the opportunity to check the time on clock with the "time ball", located on the roof of constructed in the same year a new corporate headquarters - Western Union Building. In the 80's of Nineteenth century, Western Union was repeatedly tried capture by the railroad tycoon Jay Gould. He worked with Alexander Graham Bell, inventor of the first phone. In the early 60s Western Union has put into operation transcontinental microwave system of data transmission via radio waves, completely replacing the web of telegraph poles and wires. 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. Transaction with Fexco has allowed Western Union to control directly more than 10 thousand points of service, which belonged to Fexco in 7 European countries (Spain, UK, Sweden, Ireland, Denmark, Norway and Finland). 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.
