Like its radio predecessor (which finally ended in 1954), the series focused mainly on the Nelson family at home, dealing with everyday problems. As the series progressed and the boys grew up, storylines involving various characters were introduced. Many of the series story lines were taken from the Nelsons' real life. When the real David and Rick married June Blair and Kristin Harmon, respectively, their wives joined the cast of "Ozzie and Harriet" and the marriages were written into the series. What was seldom written into the series was Ozzie's profession or mention of his lengthy and successful band-leading career. The popular joke about his career was that the only time he left the house was to go buy ice cream. According to his granddaughter, actress Tracy Nelson, Ozzie went to Rutgers to study law and when pressed would tell interviewers that the TV Ozzie was a lawyer.
