One Day at a Time is an American television sitcom that aired on CBS from December 16, 1975, to May 28, 1984. It starred Bonnie Franklin as a divorced mother raising two teenage daughters, played by Mackenzie Phillips and Valerie Bertinelli, in Indianapolis. Background The series was created by Whitney Blake and Allan Manings, a husband-and-wife writing duo who had both been actors in the 1950s and 1960s. The series was based on Whitney Blake's own life as a single mother raising her three children (including future actress Meredith Baxter) after her divorce from her first husband. Overview Divorced mother Ann Romano moves herself and her teenage daughters, rebellious Julie and wisecracking Barbara, from their home in Logansport, Indiana, to Indianapolis. Ann frequently struggles with maintaining her role as mother while affording her daughters the freedom she never had as a young woman. Dwayne Schneider, the building superintendent, provides usually unwanted advice to the tenants, especially Ann. Ann dates her divorce lawyer, David Kane, and they become engaged, but on their wedding day David says he wants kids; Ann does not, so they call off the wedding. After David takes a job in Los Angeles, the show focuses on Ann's dilemmas as single mother and career woman, as well as the girls' growing pains, with Schneider becoming a more welcome part of the family. Ann's strained relationship with her ex-husband Ed slowly improves, as does the girls' relationship with his new wife Vickie. Julie and Barbara graduate from high school and head into the working world. Julie eventually marries flight attendant Max Horvath. Alex, the orphaned son of Ann's deceased boyfriend, moves in, changing the dynamics in the female-dominated apartment. Later in the series' run, Julie gives birth to daughter "Little Annie" Horvath, Barbara marries dental student Mark Royer, and Ann's mother Katherine moves nearby. In the penultimate episode, Ann decides to take a job in London, leaving her daughters in Indianapolis raising their own families. In the series finale, Schneider also leaves town, moving to Florida to take care of his niece and nephew. Production For its entire run, the series was taped in Hollywood before a studio audience. Originally, it was taped at CBS Television City. Shortly after its premiere, the series began taping at Metromedia Square, where it remained until 1982. From 1982 to 1984, the series was taped at Universal Studios. Like many sitcoms developed by
