Document Summary

Limited to where the lines were laid. Both were privately owned but there was public regulation, especially of the telephone industry: gov. approved monopolies. Telephone is a natural monopoly: only makes sense if one company does it but you have to regulate that company, a regulated monopoly. Wired/wireless: the early radio morse code messages were very similar to telegraph, but it went into the ether and could be picked up by someone with a radio receiver somewhere else. Bi-directional: one to one: individuals have their radio sets, they tap out morse code, someone else taps out morse code back, not how radio works today. Today radio is not one to one, it is one to many. Today it is a one way model: went from bi-directional to uni-directional, central transmitter to passive receivers. Radio waves: electro-magnetic energy, radiating in waves (not wires, go very fast, could travel for hundreds of miles.
