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. By the mid-1960s, America's social climate was changing, and the Nelsons, symbolizing the 1950s values and ideals, were beginning to seem dated. Ozzie, who wrote and directed all of the series' episodes, attempted to alter the series to fit the times, but most viewers associated the series with a bygone era. The series cracked the top thirty programs in the Nielsen ratings for the first and only time in its eleventh season (1963–1964), when it ranked in 29th place. It made the transition from black-and-white to color in the 1965–66 season. That year, Ozzie tried to recapture the series' early success by introducing nine-year-old Joel Davison and other young children to relate to younger families. Although Davison appeared in three episodes, the series' Nielsen ratings continued to decline. In January 1966, ABC moved the series to Saturdays, where it completed its 14-season run that spring.
