In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. 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. You do not need to open a bank account, so you can send or receive money in any of the 170 000 service points of Western Union around the world. Western Union made so that the time in all of American civil services was the same.
