At first, two iron wires connected each pair of telephones. Then switchboards brought phone wires into one location. Other inventions - the vacuum tube to amplify sound, and coaxial cables to link long distances on land and under the seas -- greatly expanded phone service. Transistors replaced the old vacuum tubes, and by the 1960s communications satellites eliminated the necessity of landlines.
