Early Telegraph Unites Domestic Market But Not World Market

The invention by Morse of the early telegraph in the 1840s provided a means of instant communication between locations in the U.S. The telegraph thereby united the domestic market. It also allowed coordination of long-distance railroads. However, the telegraph did not reach Europe until a transatlantic cable was laid. Prices information between the U.S. and Europe flowed only by sailing ships with great delay as a result. (The first completely successful cable across the Atlantic did not come until 1866. An earlier cable failed after a short time.)
