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.
