Yet cultural boundaries do not always correspond to political boundaries subcultures sometimes exist across national borders. People who live in different nations but who share the same subculture can have more in common with one another than with their fellow nationals. Arab culture, for instance, extends from northwest Africa to the Middle East, pockets of Arabs in many European countries and the United States. Because Arabs share a common language and tend to share purchasing behaviors related to Islamic religious beliefs, marketing to Arab subcultures can sometimes be accomplished with a single marketing campaign. The company profile at the start of this chapter showed us how Harbo worked to make its product acceptable to Muslim (and Jewish) consumers worldwide.
