The idea for the show was inspired by a newspaper article.
“It's very rare that a writer knows exactly where his ideas come from,” series creator Sherwood Schwartz said. “However, in the case of The Brady Bunch, I know exactly what inspired that show. It was just a four-line filler piece in the Los Angeles Times. Just a statistic. It said that year, 1965, 31 percent of all marriages involved people who had a child or children from a previous marriage. It was just a statistic, but to me it indicated a remarkable sociological change in our country."
