In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. Separation of the companies had two objectives: first, to give Western Union the opportunity to develop more intensively, and secondly, to help First Data to return to its original activity (in 1992 the company separated from the payment system of American Express as an independent financial services company). One of the common kinds of money transfer is a transfer via the international system of Western Union. In 1879 Western Union left the telephone business after losing a lawsuit against Alexander Graham Bell - the patent holder on the phone. The Western Union Company uses the most up to date technologies and its unique worldwide computer network that allows to carry out quick money transfers payments in more than 190 countries around the world. In October 1871 the company Western Union began to provide money transfer services, drawing on its own extensive telegraph network.
