To eliminate incompatibilities in the phone network, the u. s. government granted which company a monopoly on the telephone system

From 1913 to 1984, the US government believing that Americans are entitled to affordable and reliable telephone service, AT&T functioned as a government-granted monopoly . It is a common knowledge up until now that the communication industry is a very expensive industry because of all the operating costs thus only one producer can be sustained. These costs include the telephone poles and lines, the call centers, the research and development, the repairs, and the monthly power bills, to name just a few expenses associated with running the enterprise. The costs of the mentioned items are really high. The average cost of serving each individual will tend to be reduced if a large phone company earns a lot of money and serves numerous customers. For AT&T to have the appropriate customer base, the best way to do this is to eliminate competition. Even before the 1990s, there are already a lot of energy companies in many developing nations operated as government-granted monopolies. For some time in the United States, the same reason that AT&T enjoyed this privilege.
