(4) Oprah Winfrey–Harpo Studios
Oprah Winfrey is the swan song of self-made women in America. Ms. Winfrey ran away from home at the age of 13 after years of abuse. In her teenage years, she worked at a local grocery store and later won a local beauty pageant. She got the attention of a local African-American television station, WVOL, which helped propel her career to a new and exciting level. In the early 80s, Winfrey landed a job hosting AM Chicago. The show propelled her career, as her show rivaled Donahue in the Chicago area.
