In the Western Union in the 30s of the 20th century worked 14 thousand couriers delivering telegrams. Each money transfer is protected with control number, that allows you to track and to ensure prompt payment of money specified by you person. You do not need to open a bank account, so you can send or receive money in any of the 170 000 service points of Western Union around the world. 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.
