Telco (telecommunication operators) companies have always been CSP (communication service providers) since the origin. They started and created their power along the road by implanting the infrastructure to let people communicate easily from all over the world by just dealing a number on a machine called “telephone”.
The Bell Telephone Company was founded on July, 1877. Long distance calls, at that time, were a dream. Later in 1885, Bell created the American Telephone and Telegraph company (AT&T) to create a nationwide long-distance network with a commerically viable cost-structure. The mission was to reach the mass of people. The first telephone line from Chicago to New York was inaugurated in 1892, eventually creating a content-wide telephone system. The assets of Bell Company were merged into the new AT&T.
