But if official propaganda fell into ignominy, there was no such effect on its commercial cousin, advertising. Indeed government's discontinuation of wartime media messaging, in a sense, left the field more open for business interests, who, just as they had immediately following the previous world war, filled the vacuum. After the war, commercial broadcasters would enjoy both the powers of centralized control and the perennial lure of advertising revenues.
