The show airs daily for a conservative estimate of 200 episodes each year. In a regular game there are four competitive questions for the two dueling families and five questions in the Fast Money final. For the 25 years the show’s been on in its current format there were 25 x 200 x 9 x 100 = 4.500.000 questions (supposedly) posed to members of the general public.
So … have you been one of them or do you know someone who was surveyed? Were you approached in the streets or by telephone? How many questions do they ask in a batch?
Or do they rather lock 100 voluntary subjects in a room for marathon questioning sessions?
On the original ABC version, during the first week of shows, they would display an address (I think it was just “Family Feud Survey” and then the standard Goodson-Todman LA address) to send in a postcard if you wanted to be in the survey. Supposedly, they got so many responses that it was years before they needed to do it again.
