During the first weeks of 1933, the Nazi regime deployed the radio, press, and newsreels to stoke fears of a pending Communist uprising, then channeled popular anxieties into political measures that eradicated civil liberties and democracy. SA (Storm Troopers) and members of the Nazi elite paramilitary formation, the SS, took to the streets to brutalize or arrest political opponents and incarcerate them in hastily established detention centers and concentration camps. Nazi thugs broke into opposing political party offices, destroying printing presses and newspapers.
Sometimes using holding companies to disguise new ownership, executives of the Nazi Party-owned publishing house, Franz Eher, established a huge empire that drove out competition and purchased newspapers at below-market prices. Some independent newspapers, particularly conservative newspapers and non-political illustrated weeklies, accommodated to the regime through self-censorship or initiative in dealing with approved topics.
