Select one of the four countries: Saudi Arabia, India, S. Africa and Japan — and discuss why social networks including Twitter have become so popular in the particular country. How does the profile of their online users compare to the U.S.? Do they use these two social media tools differently than Americans? The article can be from any professional online business/marketing source. Do not use Wikipedia or other source which is edited by the public - these sources are not appropriate for serious graduate-level work. The article does not have to be from an academic Journal, but it does have to come from a business publication such as Wall Street Journal, BusinessWeek, Money magazine, Advertising Age or any other respected publication. Read the article and then write a one-page summary of the article.
