Western Union has several divisions, with products such as person-to-person money transfer, money orders, business payments and commercial services. Most service points of Western Union work in the time convenient for customers throughout the week and throughout the year. 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 2007 the company made 167.7 million transactions on money transfers between individuals and 404.6 million transactions between physical and legal persons. 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. In 1849, Selden and Sibley, the founders of the future Western Union, created the New York State Printing Telegraph Company.
