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 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. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In 1995, First Financial Management was acquired by First Data Corp. (the deal amounted to $ 7 billion), and Western Union Financial Services became a subsidiary of First Data. 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.
