The Flip Wilson Show(1970 - 1974)
The Flip Wilson Show was the first successful network variety series with an African-American star. In its first two seasons, its Nielsen ratings placed it as America's second most-watched show. Flip Wilson based his storytelling humor on his background in black clubs, but adapted easily to a television audience. The show's format dispensed with much of the clutter of previous variety programs and focused on the star and his guests.
