Robert Johnson was the founder of Black Entertainment Television (BET) and the first African American billionaire. He was born in 1946 in Mississippi and grew up in Illinois. He earned degrees from the University of Illinois and Princeton University. After seeing that black audiences were underserved on television, he convinced cable executives to fund BET, which launched in 1980. BET grew rapidly and Johnson sold it to Viacom for $3 billion in 1998, making him the first black billionaire. He has since founded other successful companies targeting underserved markets.
