Northwestern Bell

Northwestern Bell was an American Midwestern telephone company. It was operated for Iowa, Minnesota, Nebraska, North Dakota and South Dakota. The company began as Nebraska Telephone Company and Iowa Telephone Company.
In 1920, these and three other telephone groups were merged into one company and renamed Northwestern Bell Telephone Company. When the Bell System was phased out, it was renamed to Northwestern Bell a US WEST Company.
Between 1990 and mid-1994, the Northwestern Bell name stopped being used. It was replaced under the US West Communications company banner. In 2010 or 2011, CenturyLink took over the Northwestern Bell name and the operations. At that same time, CenturyLink replaced the Qwest name.
