In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. 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). By 1861 Western Union telegraph lines entangled the whole America. It's time to explore Europe. 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. All you need for sending money via Western Union is to go to the nearest branch of Western Union, fill out the transfer printed form, show your passport and then send money. Sibley, the founder of Western Union, did not build a new telegraph lines, and persuaded the other players to join. American Telegraph Company, however, still had to buy it.
