에이티앤티(AT&T) - 세일즈맨

Company formation and expansion

In 1880, the management of American Bell created what would become AT&T Long Lines. The project was the first of its kind to create a nationwide long-distance network with a commercially viable cost-structure. This project was formally incorporated into a separate company named American Telephone and Telegraph Company on March 3, 1885. Starting from New York, the network reached Chicago, Illinois, in 1892.

Bell's patent on the telephone expired in 1894, but the company's much larger customer base made its service much more valuable than alternatives and substantial growth continued.
