The Murdoch Family
The Murdoch family might have ancestors from Australia, but their success and fortune were made in America. Rupert Murdoch took the American citizenship oath in 1985, making him an American. Currently, Murdoch controls Fox Broadcasting Company, Fox Television Stations, Fox News, the Fox Business Network, Dow Jones & Company, Wall Street Journal, MarketWatch, News Corp Australia, Fox Sports Australia, New York Post, HarperCollins, and even News America Marketing. The family is sitting nicely on $17.9 billion.
