Описание:
Communication was revolutionized when, in 1844, Morse strung a wire 40 miles from D.C. to Baltimore. The successful transfer of a tapped out message signaled a new age of singing wires that quickly connected the continent. Imagine the difference by comparing a telegram to the pony express, suddenly California is a lot closer. The invention even connected North America to Europe when, in 1858, Cyrus Field, strung a cable across the Atlantic connecting continents. These are truly the origins of the current global telecommunications revolution of which the United States has become the vanguard.
