The Brady Bunch is an American television sitcom starring Robert Reed, Florence Henderson, and Ann B. Davis, which revolves around a large blended family. The show originally aired from September 26, 1969, to March 8, 1974, on ABC and was subsequently syndicated internationally.
In 1965, following the success of his TV series Gilligan's Island, Sherwood Schwartz conceived the idea for The Brady Bunch after reading in the Los Angeles Times that "40% of marriages had a child or children from a previous marriage." He set to work on a pilot script called Mine and Yours and passed it around the "big three" television networks of the era. ABC, CBS and NBC all liked the script but each network wanted changes before they would commit to filming and Schwartz shelved the project.
Despite the similarities between the series and the 1968 theatrical release Yours, Mine and Ours starring Henry Fonda and Lucille Ball, the original script for The Brady Bunch predated the script for the film. However, the success of the film was a factor in ABC's decision to order episodes for the series.
