Telegraph machine ticker

The telegraph ticker was a mechanical device that transmitted real-time stock quotes and news via telegraph, revolutionizing financial markets in the 19th century.

About this subject

The telegraph ticker, also known as a ticker tape machine, was invented by Edward A. Calahan in 1867 and patented in 1869. It enabled stock prices to be transmitted quickly from Wall Street to offices throughout New York City, eliminating the need for messengers. The device worked by receiving electrical signals from the telegraph and printing letters and numbers on a long strip of paper, which brokers read. The distinctive clicking sound of the machine gave rise to the term "ticker." The New York Stock Exchange adopted the system widely, and the ticker soon became an icon of modern capitalism. Interestingly, the phrase "ticker tape parade" originates from these machines, as the used ticker tape was thrown from windows during celebrations. The ticker was gradually replaced by electronic systems in the 1960s, but its legacy endures. Calahan's invention transformed the speed of financial information, allowing investors to make faster and more informed decisions.
