In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. Leaving the idea of expansion into Europe, Western Union took up the expansion of services in the U.S. market. Most service points of Western Union work in the time convenient for customers throughout the week and throughout the year. In the early 60s Western Union has put into operation transcontinental microwave system of data transmission via radio waves, completely replacing the web of telegraph poles and wires. In October 2006 the company made an initial public offering of shares on the New York Stock Exchange, becoming independent from First Data company. 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 2000 was launched the Web site westernunion.com, with which users from certain countries can independently transfer funds online. Western Union made so that the time in all of American civil services was the same.
