WWII ... (Spam) ...seems to have been happily received. Any ideas, gang?

Yes, it _was_ received happily - mainly, I think, because it had as competitors snoek and whalemeat. When the war ended, we gradually were able to get "butchers meat" (i.e., fresh meat - or fairly fresh, anyway ) and Spam, in those days when few households had refrigerators over here, was seen as greasy and unappetising. Personally, I never actually disliked it, but will readily admit that it came fairly way down on my lsit of preferred meats!
