On November 15, 1867, exactly 150 years ago today, the Wall Street started ticking, literally, with the brainchild of Edward Calahan, who configured a telegraph machine to print stock quotes on streams of paper tape.
It was the day the first stock ticker got unveiled in New York City with tremendous results.
The stock ticker color-graphed current stock prizes brokerage houses across the United States hence revolutionized the stock exchange by transmitting information at real time to investors.
Before the advent of the stock ticker, information from the New York Stock Exchange, which has been around since 1792, traveled by mail or messenger.
