The Doris Day Show is a classic American sitcom that aired on CBS from 1968 to 1973. The series follows Doris Martin, a widow who decides to leave her hectic life in San Francisco to move back to her father's ranch in Mill Valley with her two young sons, Billy and Toby. The show is notable for its frequent format changes, as it evolved from a rural-themed family comedy into a more sophisticated urban sitcom as Doris eventually moves back to the city to work as a secretary at a magazine. Throughout its five-season run, the series navigated the changing landscape of 1960s and 70s television. While the early seasons focused on the domestic dynamics of ranch life and the relationship between Doris and her father, Buck Webb, the later seasons shifted focus to Doris's professional life and her interactions with her eccentric boss, Cy Bennett. Despite the shifting premise, the show remained a vehicle for Doris Day's charm and musical talent, often featuring her in lighthearted, comedic situations.
