Telegraphy came to Europe when The Telegraph Company (now: British Telecom) established its first telegraphy line in 1849.
Norway started early to build a telegraphy network: Den Norske Statstelegraf (Norwegian Telegraph Administration, now Telenor) was founded in 1855. The first Norwegian telegraph line, between the capital Christiania (now Oslo) and the nearby city of Drammen, was opened the same year.
Twelve years later, in 1867, the first international telegraph line came into operation between Norway and Denmark, and from 1870 Norway was one of the first European countries with nationwide telegraphy coverage.
The extensive Norwegian fishing industry was a driver for the telephone companies in their fast development of telegraphy coverage and services.
