The Brady Bunch is an American sitcom created by Sherwood Schwartz that aired from September 26, 1969, to March 8, 1974, on ABC. The series revolves around a large blended family of six children, with three boys and three girls. After its cancellation in 1974, the series debuted in syndication in September 1975. Though it was never a ratings hit or a critical success during its original run, the program has since become a popular syndicated staple, especially among children and teenage viewers.
