You may know journalist Geoff Bennett as co-anchor of the 'PBS Newshour,' or as a contributor to NPR and NBC. He is also the author of the new book 'Black Out Loud: The Revolutionary History of Black Comedy from Vaudeville to ‘90s Sitcoms.' Bennett tells The Treatment why the '90s was a ‘golden age’ for Black TV, how the 'Cosby Show' spinoff 'A Different World' evolved, and why many people got Steve Urkel wrong.
