On November 15, 1867, the first stock ticker was unveiled in
New York City. The advent of the ticker revolutionized the
stock market by making up-to-the-minute prices available
to investors around the country.

Prior to this development, information from the New York
Stock Exchange, which has been around since 1792,
traveled by mail or messenger.

The ticker was the brainchild of Edward Calahan, who
configured a telegraph machine to print stock quotes
on streams of paper tape (the same paper tape later
used in ticker-tape parades).

The ticker, which caught on quickly with investors, got
its name from the sound its type wheel made.

The First Stock Ticker – Postcard.

Black Tuesday hit Wall Street on October 29, 1929 as investors
trade 16,410,030 shares on the New York Stock Exchange in a
single day. Billions of dollars were lost, wiping out thousands
of investors, and stock tickers ran hours behind because the
machinery could not handle the tremendous volume of trading.

In the aftermath of Black Tuesday, America and the rest of the industrialized world spiraled downward into the Great
Depression.
