+year outright monopoly on the telecommunications industry and infrastructure in
+the US. Inclusive of the American Telephone and Telegraph Company (AT&T), AT&T
+Long Lines (line network), the Western Electric Company (manufacturing
+telephonic equipment), and Bell Labs (the R&D section). Each major city/ region
+had a subsidiary, e.g. Michigan Bell, Northwestern Bell, the New York Telephone
+Company etc.
+
+Colloquially known as "Ma Bell" ("mother Bell").
+
+The monopoly was broken up in 1983. Today, after the breakup the remaining (now
+separate) companies are AT&T (phone network, mobile network), Verizon (mobile
+network), and Lumen (cloud computing, networking services).
