When it was first conceived, The Brady Bunch was the story of a lovely lady — who was bringing up three very lovely girls — and the the story of a man named Brady — who was busy with three boys of his own. And as one of the show’s original writers revealed, it was only after the first season aired that producers realized the Brady kids, rather than their parents, were the real stars of the show.
Lloyd Schwartz, son of Brady Bunch creator Sherwood Schwartz and a writer and producer on the show, shed light on that origin story on the podcast The Real Brady Bros in 2022, per People.
