Abstract
Until the mid-1800s, communicating over distances meant waiting long periods of time between transmission and reception. Visual signal systems such as the semaphore (a system using torches or flags to convey meaning) used by the Romans1 and the French2 and smoke signals used by Native Americans were rapid, but the amount of information that could be transmitted quickly and effectively was limited.
