Know-How Exchange : Student Questions

I am writing an essay on cultural distance and its impact on global marketing management. As part of mine work, I need a range of examples how cultural distance affects global marketing operations, for example a product having to be altered to meet consumer demand in different countries, or how particular global brands adapt regional strategies in order to meet consumer demand. All in all, I need some examples showing how culture affects implementing marketing strategies. It would be quiet useful, if I have the opportunity to give examples for failed marketing campaigns due to ignorance of culture, ads that were banned in particular countries, and brands that operate on local level.
