On 9 April 1940 Norway was invaded by Nazi Germany, and an occupation started. Two days after the invasion, "Fritt Folk" was sent out as a supplement to popular newspapers such as "Aftenposten". This ended on 15 April when Quisling was intermittently deposed and the Administrative Council was installed, but the newspaper continued to prosper under Nazi rule. It had certain competitors in that many existing newspapers were usurped by Nazis, including "Aftenposten", and they brought the same kind of news as "Fritt Folk". Other newspapers were stopped, and when "Arbeiderbladet" was stopped in August 1940, "Fritt Folk" usurped its offices and printing press. A prerogative for "Fritt Folk" was that Norwegian businesses and companies were forced to advertise in the newspaper, which boosted the economy. The circulation was secret, and this and some other administrative aspects of the newspaper has not yet been unveiled.
