Part I — The story
The story
Alexander Graham Bell invented the telephone and secured, in 1876, what became one of the most valuable patents ever granted. A teacher of the deaf whose work on sound and speech led him to transmit the human voice electrically, Bell won a famous race to the patent office and then built the Bell Telephone Company, which grew into the vast AT&T telephone monopoly.
Bell's achievement combined genuine invention with the crucial business step of patenting and commercialising it fast. The telephone network he founded became a textbook network effect — each new telephone made every other one more valuable — and grew into one of the most powerful companies in the world. Bell himself moved on to restless invention across many fields.
Bell shows the decisive importance of the patent and the network: he not only invented the telephone but secured ownership and built the network whose compounding value created an enduring monopoly.
