# Bell System
|
|
|
|
Denotes the family of companies run by the Bell Telephone Company during its 100
|
|
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).
