Featured on a site mentioned here earlier but interesting stuff, I think.:
Coca Cola GmbH sought to be associated with the Nazis, it became a bit of a joke that if Hitler or a high ranking Nazi was on the front cover of a magazine Coke would advertise on the back. Coke advertised on billboards that were by the Berlin stadiums, so people attending Goebbel's rallies had to walk past them.
Coke financially supported the Nazis by advertising within Nazi newspapers, in one instance Coke published responses to accusations from rival bottlers that they were a Jewish company. These denunciations were placed in Nazi rags.
Coke advertised in the Nazi Army paper shortly after the invasion of Sudetenland, the ad was a picture of a hand holding a bottle of coke over a map of the world, the slogan was "Yes we have got an international reputation."
Coca Cola goes to war, on BOTH sides.
