In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. In 1866, Sibley ordered the engineers to develop a Western Union telegraph system of stock quotes in real time. 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. In 1849, Selden and Sibley, the founders of the future Western Union, created the New York State Printing Telegraph Company.
