Title: From invention to innovation
Description: By the late nineteenth century, American Bell Telephone had expanded its services across much of the United States. Yet transmission was difficult through overhead wires over distances of more than a few hundred miles, and impossible in cables beyond thirty miles. Wasserman studies the inventions and innovations that made extension possible.
