In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In 1860 the U.S. Congress arranged among the telegraph companies a competition to create a national line. The winner was Western Union. In 1995, First Financial Management was acquired by First Data Corp. (the deal amounted to $ 7 billion), and Western Union Financial Services became a subsidiary of First Data. July 3, 1884 the company's shares were included in the calculation base for the newly created stock index Dow Jones Transportation Average. In 1849, Selden and Sibley, the founders of the future Western Union, created the New York State Printing Telegraph Company.
