The day of deregulation for the securities market in London, England, when the London Stock Exchange became a private limited company. The event revitalized the London Stock Exchange, as outside corporations were allowed to enter its member firms and automated price quotation was established.
Investopedia Says:
Before the big bang, the London Stock Exchange was trailing the other major exchanges in the world. At the time, the New York Stock Exchange was listed as the No.1 market worldwide, determined by turnover rate. London was only able to turn over one-thirteenth of the volume transacted by the New York Stock Exchange. The adaption of an electronic trading system helped improve London's turnover, as orders were accepted by telephone and computer.
