Stock Ticker Machine
The stock-ticker machine was a device very much like the present-day digital stock ticker. It was a ticker-tape machine that would continuously send updates on stock prices to traders not physically on the Stock Exchange floor. This version/use of the ticker-tape machine helped to close the gap between time and space in the business world, helping to improve the economy.
INVENTION AND USES<b>
The original stock-ticker claims to be invented by two different people. One was Frank Pope, then the general manager of the Gold & Stock Reporting Telegraph Co. The other was Edward A. Calahan, whose version fronted the Gold Stock Telegraph Co. Both were created in the 1860s, Calahan's in 1867 (Sobel).
