Stock ticker
about 1900
made by the Western Union Telegraph Company
The U.S. economy grew rapidly after the Civil War, fueled by an astounding rise in wealth, wages, production, and corporate mergers, along with limited government regulation. The volume of stocks traded rose sharply with corporations' need for investment capital and the development of new technologies. The 1867 invention of the stock ticker, transmitting up-to-the-minute share prices over telegraph lines, modernized the stock exchange. |
