Darrin Stephens – Bewitched

On Bewitched, Dick York initially played the role of the husband for five seasons, but the show replaced him with Dick Sargent so that York could recover from chronic back pain problems. This did not go over well with fans.

Bewitched was the second-rated show in the country during its first season, was in the top ten for its first three seasons, and ranked eleventh for seasons four and five. Then upon York’s departure, and it was never rated that high again.
