In their founding days, stock exchanges were run as auctions, one stock at a time offered to an audience of bidders. As the demand for capital (and the number of stocks) grew, stockbrokers had to develop ways of selling and buying multiple stocks simultaneously. This need to do everything at once increased the stakes tremendously and drove financiers to find ways to keep track of an incredible volume of simultaneous transactions and make the best transaction at any given moment. The flows of information produced by flows of capital have kept growing and speeding up, creating the need for better and faster tools for tracking information.
