Richard Dawson hosted the show on two separate stints, from 1976 to 1985, and then again from 1994 to 1995.
The Game Show Network, which broadcasts reruns of old game shows, only airs the Steve Harvey years of “Family Feud”, which are considered by some people to be some of the worst programming on television for the intended demographic to whom it is aimed (due to its often raunchy, filthy, and/or adult-themed content).
Of course, the simplest answer is that filth gets ratings, but beyond that, there is still good, wholesome and nostalgic programming that attracts viewers.
