When introducing a product to another country or culture you have to be careful to not offend anybody. Things seen here and done here may be offensive elsewhere. Things here may need to be altered slightly to sell and be presentable in other places. Understanding my culture helps you understand others because you know what your beliefs and values are and you can see how much they mean to you. So understanding and knowing another person's culture could be important when trying to market something or just understand one's lifestyle.
