Ehm I'm not really sure how anyone of us is supposed to know that unless that has been researched and as a result there is factual data present.
I live in Belgium, Europe and I know that the concepts of 'manga' and 'anime' are still something for a specific social group and not something that is wide spread. The only anime of the known series that so far has aired, is Naruto and not the most ideal moment of the day. No idea how it is in other European countries, but I get the impression that in countries like France and Spain it's much more integrated in society than here.
