That's So Raven wasn't the first live-action black sitcom. Good Times and The Cosby Show did that long before that show premiered. Anyway, it was a great show. I loved watching it as a child. "Feelin' the Love" is my jam.
Sister, Sister, Kenan and Kel opened those doors for her. But she did set the standard for Disney sitcoms. She definitely opened the door for Nick to have their first black female lead with True Jackson, VP. Slay Rae!
