The major national news agency, Norsk telegrambyrå - NTB , was established in 1867. The press now collectively owns the agency. In addition to the newspapers, major radio and television channels subscribe to its services. But a reduced interest in national and international news, has reduced the revenues for the company.
Early in the 20th century the Labour Party press established its own press agency, distributing news and propaganda. In the post-war period other political parties established their own agencies. Most of these agencies disappeared when the era of the party press ended. Only the Social Democrat agency survived, called Avisenes nyhetsbyrå (ANB. There was a strong competition between NTB and ANB. This ended in 2006-2007, when NTB took over all general news services. ANB maintains only specialised and limited services.
