Telegraph machine ticker

The telegraph ticker, also known as the stock ticker machine, revolutionized the transmission of financial information in the 19th century.

About this subject

The telegraph ticker, invented by Edward A. Calahan in 1867, was a milestone in the history of communications. The machine used telegraph signals to print stock quotes and news on a paper strip, known as ticker tape. This device allowed investors and brokers to track prices in real time, eliminating the need for messengers and delays. The machine became a symbol of the New York Stock Exchange and other financial centers worldwide. The technology evolved into electronic tickers, but the term "ticker tape" is still used in confetti parades, inspired by the paper strips thrown from windows during celebrations. The original machine worked with a keyboard that transmitted Morse code to a receiver that printed characters on a continuous tape. The printing speed was about 1 character per second, yet it was revolutionary for its time. The telegraph ticker was gradually replaced by electronic systems in the 1960s and 1970s, but it left a lasting legacy in how financial information is disseminated.
