Family Tree of Telecommunication

Note: Despite its size, this family tree chart is woefully incomplete and grossly oversimplified. Not shown are the various minor subsidiaries, independent local phone companies today and the hundreds of early phone companies that had gone out of business trying to compete with "Ma Bell."

Since the very first telephone companies were founded, it seems that telecommunication companies never do business as just one entity when ten would do. Whatever the reason - be it compliance with local regulations, taking advantages of tax loopholes, obfuscation or simply fondness of complexity - subsidiaries and complex corporate structures are the raison d'être for these companies.
