In the post-war period, there were good prospects for a policy for sport that built on the ideas developed by the Workers Sports League (AIF). In keeping with AIFs ideology, public authorities were given a central role in the democratic distribution of sports facilities. As head of the new Office for Sport, Rolf Hofmo had considerable freedom of action, not least in connection with the creation of a national betting company, Norsk Tipping, in 1946. The article casts light on policy development in the interaction between the sports organisations and the state in the inter-war period. The central question was how sports facilities should be financed, managed and spread. The relations between sport organisations and the state changed in the period 1917–40. Sports organisations were drawn into the design and implementation of a system of management. The process is described from the starting point of the opposed interests of the two sports organisations, Arbeidernes Idrettsforbund (1924–1940) and Landsforbundet (1919–1940), and the role of the state in regard to this conflict. A corporative style of management was developed. The relative power of sports organisations and the state, and particularly the changes in this respect after the sports agreement of 1936, had great significance for the design of the management system which was in many ways continued after the war.
