In the early forties of the 20th century, Western Union has used the first time a commercial intercity microwave transmission system. In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. 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. Transaction with Fexco has allowed Western Union to control directly more than 10 thousand points of service, which belonged to Fexco in 7 European countries (Spain, UK, Sweden, Ireland, Denmark, Norway and Finland).
