Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. 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. In October 1871 the company has implemented the world's first telegraph money order. After a century money transfers have become a major source of income for Western Union.
