Old and New Technology
Old inventions are not necessarily eliminated by the new ones. After all, people did not stop riding bicycles after the car was invented. Thus, older inventions may be replaced, but they seldom disappear because new roles are created for them. Some of the best examples of this are from the field of long-distance communication. Until the 19th century, communication had been limited by distance and time. Then, it came a series of amazing inventions that extended the range of human communication.
