I was googling this question when I stumbled across this subreddit, and it seemed like a good place to ask. I'm looking for primary or secondary sources about German coverage of the atom bomb dropping (I've already located coverage from America, Britain and Japan.) I'm using this info to write a paper for a media history class. Thanks in advance to anyone who can help.
The crux to this question is that there was no independent German media when Hiroshima was bombed.
Germany had surrendered months earlier, all radio stations, cinema newsreels and most newspapers were directly controlled by the Allies. Those few media outlets that weren't, all of them newspapers, had to obtain a licence, were supervised by Allied officers (sometimes even partially staffed by delegated soldiers who spoke German) and were subject to heavy censorship - in August '45, these newspapers were the Aachener Nachrichten, Frankfurter Rundschau, the Berliner Zeitung, Badener Tageblatt, Saarbrücker Zeitung and finally the KPD papers Volk and Deutsche Volkszeitung.
To obtain a licence you had to conclusively prove that you did not work for any of the state or party media in existence between '33 and '45, which, thanks to their subordination to the Reichskulturkammer was most of them - about 85% of all newspaper issues sold in '44 were printed under direct NSDAP control. Thus most of the printers who gained a licence were drawn from a political spectrum that was firmly opposed to the thoroughly nazified news media that had existed prior to '45 - and even then it was required that prior to being published, every issue was to be submitted to the Allies for approval, who preferred to keep political and war topics to a minimum.
Overall this makes it very hard to speak about a "German" media reaction to the bombing of Hiroshima, as there is almost no way to prove what was filtered out or added by the Allied occupation force.
