Dick Van Dyke, fresh from headlining his own short-lived Emmy-winning variety series, "Van Dyke & Company", was brought in to replace Korman. However, his presence did not help stem the sagging ratings, as the show faced new competition in ABC's "The Love Boat". After three months, Van Dyke departed the show, and CBS, in a desperate attempt to save the series, moved "The Carol Burnett Show" from Saturdays at 10:00 pm (EST) to Sundays at the same hour, beginning in December 1977. Regular guest stars Steve Lawrence and Ken Berry were brought in to fill the void left by Korman and Van Dyke. The ratings improved considerably.
