In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Western Union has several divisions, with products such as person-to-person money transfer, money orders, business payments and commercial services. Another invention of Western Union - time synchronization. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In October 1871 the company Western Union began to provide money transfer services, drawing on its own extensive telegraph network.
