Several conservative members of Congress, as well as President Richard Nixon and members of his administration, expressed displeasure at some of the replacement shows, many of which (especially the more socially conscious shows such as "All in the Family") were not particularly "family-friendly". The backlash from the purge prompted CBS to commission a rural family drama, "The Waltons", for its fall 1972 schedule based on the TV film "The Homecoming: A Christmas Story" (1971). The network scheduled it in what it thought would be a death slot against popular series "The Flip Wilson Show" and "The Mod Squad", allegedly hoping the show would underperform and head to a quick cancellation. Instead, the show proved to be an instant hit, prompting CBS to change course and put its full support behind the show; "The Waltons" went on to run for nine seasons, reaching as high as second in the Nielsens and finishing in the top 30 for seven of its nine years on air, and would become a perennial fixture in syndicated reruns for decades thereafter. The success of "The Waltons" started a trend for family dramas throughout the 1970s; such as "Little House on the Prairie", "Apple's Way", "Family", and "Eight Is Enough".
