In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. Money transfer is a matter of minutes, at any distance. In 1856, in 7 years after the foundation of New York State Printing Telegraph Company, the company changed its name to Western Union Telegraph Company. 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.
