Dagsavisen is a daily newspaper published in Oslo, Norway. The former party organ of the Norwegian Labour Party, the ties loosened over time from 1975 to 1999. It has borne several names, and was called Arbeiderbladet from 1923 to 1997. Eirik Hoff Lysholm is editor-in-chief. The newspaper depends on economic support from the Norwegian Government. History Dagsavisen was established by Christian Holtermann Knudsen in 1884 under the name Vort Arbeide ('Our Work' in archaic Riksmål), and was affiliated with the trade union center Fagforeningernes Centralkomité. Holtermann Knudsen also had to establish his own printing press since the existing printing presses did not want to be affiliated with a labourer's newspaper. The fledgling project was marred by economic problems, and the burden of writing, editing, and printing lay chiefly on Knudsen. In 1885 the newly founded association Socialdemokratisk Forening formally took over the newspaper. The name was changed from Vort Arbeide to Social-Demokraten ('The Social Democrat') in 1886. The next year, the Norwegian Labour Party was founded, and Social-Demokraten became its official party organ. Carl Jeppesen took over as editor-in-chief. In 1894 the newspaper was published on a daily basis, and in 1904 the financial balance was positive. Around 1920 there were tensions in the Labour Party. The radical wing spearheaded by Martin Tranmæl and Kyrre Grepp had assumed control over the party at the 1918 national convention. The party aligned itself with the Comintern. As a result, a moderate wing broke out in 1921 to form the Social Democratic Labour Party. Nonetheless, Social-Demokraten remained affiliated with the Labour Party, as Martin Tranmæl assumed the editorship in 1921. In 1923, the same year as the Labour Party renounced the Comintern and the communist wing broke away, Social-Demokraten changed its name to Arbeiderbladet (lit. 'The Worker Paper') in 1923. The factionalism was contrary to the goal of Christian Holtermann Knudsen, who wanted to unite the fledgling labour movement. In 1940, upon the German invasion and subsequent occupation of Norway, Arbeiderbladet was stopped by the Nazi authorities. The only legal party in Norway during the occupation, Nasjonal Samling, evicted Arbeiderbladet from its premises, using it as headquarters for its party organ Fritt Folk. Arbeiderbladet's printing press was also utilized by Fritt Folk. Only in 1945, upon the liberation of Norway, did Arbeiderbladet resume publication. Olav Larssen, imprisoned during the occupation, was promoted from news editor as he succeeded Martin Tranmæl as editor-in-chief in
