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. 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. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average.
