paragraph_text: East German literature is the literature produced in East Germany from the time of the Soviet occupation in 1945 until the end of the communist government in 1990.

As a result, the literature of the German Democratic Republic (East Germany) was for decades dismissed as nothing more than "Boy meet Tractor literature", but its study is now considered a legitimate field. Because of its language, the literature is more accessible to western scholars and is considered to be one of the most reliable, if not the most reliable, sources about East Germany.

paragraph_text: Murdoch has responded to some of the arguments against the newspaper by saying that critics are "snobs" who want to "impose their tastes on everyone else", while MacKenzie claims the same critics are people who, if they ever had a "popular idea", would have to "go and lie down in a dark room for half an hour". Both have pointed to the huge commercial success of the Sun in this period and its establishment as Britain's top-selling newspaper, claiming that they are "giving the public what they want". This conclusion is disputed by critics. John Pilger has said that a late-1970s edition of the Daily Mirror, which replaced the usual celebrity and domestic political news items with an entire issue devoted to his own front-line reporting of the genocide in Pol Pot's Cambodia, not only outsold The Sun on the day it was issued but became the only edition of the Daily Mirror to ever sell every single copy issued throughout the country, something never achieved by The Sun.
