Robert Johnson Profile Bob Johnson, the founder of Black Entertainment Television, is America's first black billionaire. He's a busy man, having recently sold BET to media conglomerate Viacom while making plans to buy a small spinoff airline. As NPR's Snigdha Prakash reports, the 54-year-old Johnson has delighted many blacks and angered many others. He's an avowed capitalist who says he's more interested in building market value than in social policy. And he makes no apologies for the rap videos that have been the staple of his network.
