Of the 1,226 people who made it to the 2012 Forbes list of the world's billionaires, only six are black, and only one is a household name in the United States: Oprah Winfrey. With $2.7 billion, she's still the world's richest black woman, despite a tough year for her OWN television network and a quite a bit spent on her African Leadership Academy and other charitable endeavors.
Winfrey joins Mohammed Al-Amoudi (Saudi Arabia, $12.5 million); Aliko Dangote (Nigeria, $11.2 billion); Mike Adenuga (Nigeria, $4.3 billion); Patrice Motsepe (South Africa, $2.7 billion); and Mo Ibrahim (United Kingdom, $1.1 billion) on the list.
