Cosby strikes gold with "The Cosby Show," a genre-defining family sitcom and monument to Black excellence. Throughout the 1980s and 1990s, he parlays our affection for his characters into even more affection for him and leverages his growing power inside the entertainment industry to allegedly commit and conceal a multitude of sins. As the beloved sitcom comes to an end, Cosby’s persona warps from America’s Dad into America’s Angry Grandpa.
