In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. One of the common kinds of money transfer is a transfer via the international system of Western Union. In October 1871 the company Western Union began to provide money transfer services, drawing on its own extensive telegraph network.
