Happy Birthday, Oprah!
There’s no denying that Oprah’s a force to be reckoned with. From 2004 to 2006, she was the world’s only African-American billionaire on Forbes’ international list. And since she was the first black woman billionaire in world history, it only made sense for her to be named “one of the most influential people” by TIME for eight years in a row. But most importantly, Forbes named Oprah the world’s most powerful celebrity in 2005, 2007, 2008, and 2010.
