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. Thanks to cooperation with Western Union the Associated Press at the end of the XIX century took almost monopolistic position in the U.S. market news. The first offices of company were located in the Reynolds Arcade building in Rochester, New York. The sign above the main entrance to the building - Sibley, the founder of Western Union, did not build a new telegraph lines, and persuaded the other players to join. American Telegraph Company, however, still had to buy it.
