Oprah Winfrey (born Orpah Gail Winfrey; January 29, 1954) is an American media proprietor, talk show host, actress, producer, and philanthropist. Winfrey is best known for her self-titled, multi-award-winning talk show "The Oprah Winfrey Show" which was the highest-rated program of its kind in history and was nationally syndicated from 1986 to 2011. She has been ranked the richest African-American of the 20th century, the greatest black philanthropist in American history, and was for a time the world's only black billionaire. She is also, according to some assessments, the most influential woman in the world.
Winfrey was born into poverty in rural Mississippi to a teenage single mother and later raised in an inner-city Milwaukee neighborhood. She experienced considerable hardship during her childhood, claiming to be raped at age nine and becoming pregnant at 14; her son died in infancy. Sent to live with the man she calls her father, a barber in Tennessee, Winfrey landed a job in radio while still in high school and began co-anchoring the local evening news at the age of 19. Her emotional ad-lib delivery eventually got her transferred to the daytime-talk-show arena, and after boosting a third-rated local Chicago talk show to first place, she launched her own production company and became internationally syndicated.
