The Brady Bunch (1969 - 1974)
A widower with three sons marries a widow with three daughters. It's a sitcom family for the ages, with plenty of warmth and fuzziness (and constant fighting for the bathroom). The series debuted in 1969, but in many ways was a throwback to the '50s. It originally ran for five seasons on ABC, has remained popular in syndication and inspired theatrical (and TV) movies and a number of spin-offs. The series was created by Sherwood Schwartz, who also conceived `Gilligan's Island.'
