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. 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 1933, by the Western Union Company were invented "singing telegrams". In 1914 Western Union engineers invented the first payment card - a prototype of the modern credit card. In 1879 Western Union left the telephone business after losing a lawsuit against Alexander Graham Bell - the patent holder on the phone. Western Union made so that the time in all of American civil services was the same. Western Union for more than 130 years provides money transfer services to its customers.
