Telegraph machine ticker

The telegraph machine ticker, invented in the 19th century, revolutionized stock quote transmission and gave rise to ticker tape parades.

About this subject

The telegraph machine ticker, also known as ticker tape, was a device that automated the transmission of stock quotes and financial news. Invented by Edward A. Calahan in 1867 and improved by Thomas Edison, the ticker printed company symbols and stock prices on a narrow paper strip, allowing investors to follow the market in real time. Before that, quotes were delivered by messengers or published in newspapers with delays of hours or days.

The name "ticker" comes from the sound the machine made while printing, a rhythmic ticking. Each machine was connected to the New York Stock Exchange (NYSE) via telegraph lines, and the tape was fed continuously. For decades, the ticker was the main source of market information, especially in the famous Wall Street district.

A cultural curiosity: ticker tape parades originated when, during celebrations, people threw used ticker tape from office windows. This custom became a New York tradition to honor heroes, astronauts, and championship teams. Although the mechanical ticker was replaced by electronic systems in the late 20th century, its legacy remains as a symbol of the speed of financial information.
