Which game show pitched two families against each other?

Family Feud is an American television game show created by Mark Goodson. It features two families who compete to name the most popular answers to survey questions in order to win cash and prizes. The show has had three separate runs, the first of which started in 1976. Its original run from 1976 to 1985 aired on ABC and in syndication, with Richard Dawson as host. The game features two competing families, each represented by five members (reduced to four contestants for the 1994–95 season), who compete to determine the answers to survey questions. The original version of the show began with the families being introduced, seated opposite each other as if posing for family portraits, after which the host interviewed them.
