The General Post Office GPO was officially established in Calcutta in 1868 by Walter B Grenville and grew to combine the functions of the system postal status and operator of telecommunications . Similar General Post Office were set up in all the British Empire. In 1985 the organization was split into two entities the Department of Posts and Department of Telecommunications.
It was in the Greek style, with arcades ionic and measured approximately 364 m in length and 73 m in width. When in the nineteenth century and early twentieth were created new forms of communication, GPO claimed monopoly rights on the basis of the fact that, like postal services, provided for the delivery from a sender to a recipient.
The theory was used to extend state control of the postal service to any form of electronic communication possible, based on the fact that each sender used some form of distribution service. These services were considered from a legal standpoint as the post office in electronic form. This was true for the stations of the telegraph and telephone switchboards.
Originally, the GPO had a monopoly of the dispatch of items from a specific sender to a specific receiver, which would be of great importance with the invention of new forms of communication. The postal service was known as the Royal Mail because it was built on the distribution system of real documents and government.
The GPO created a network of post offices where senders could deliver objects. All mail from the post office was transferred to distribution points called switching stations, and then the mail started to be delivered to the recipient. Initially it was the recipient who paid the fare, and had the right to refuse to collect the goods if you do not wish to pay.
The rate was based on the distance traveled by the object and then the GPO had to keep a separate account for each of them, which incorporated two key innovations a uniform postal rates, which cut administrative costs and encouraged the use of the system, and prepaid adhesive postage stamps.
