Ray Combs and Richard Dawson both died on June 2 — Combs in 1996 and Dawson in 2012.
Adored by the Network: Specifically, the Harvey version, by GSN. Since it started airing in March 2012, it has gotten obscene amounts of ratings for the network, leading to not only it being adored, but Steve Harvey as well. It currently airs 58 times a week on the channel, but it used to air a lot more.
Beam Me Up, Scotty!: It's "survey said", not "says", and it's only ever used in Fast Money (never in the main game). However, this is said in Family Fortunes in all rounds.
Since Double questions returned, the question may be swapped out (or otherwise modified). If a family sweeps the first two rounds, a swept Double will almost always be less than the amount needed to win. If the Singles are split, a swept Double will always be enough for what would have been a winning scenario.
If a team does win after the Double, a commercial break is added to the Fast Money round before the second contestant returns to the stage.
In past versions, rounds were discarded due to malfunctions (two answers being revealed at once), or outside influence (someone offstage yelling out an answer). In the Harvey era, rounds have been played with no problem, only to be abruptly discarded after the third Strike because not enough points were revealed. This is known to have happened with at least one Single and one Triple, the latter because the points revealed weren't enough to win and the opponents had 0 (although the reason cited was "not wanting to look like they were showing favoritism").
At least one team in the Karn era has entered sudden death with 0, and Richard himself stated that they would need to find the #1 answer for two sudden death questions to win the game.
Blurring the line between this trope and Recycled Soundtrack, the last bar of the original Feud theme is also used to introduce Grand Game on The Price Is Right, and was a victory cue on the aforementioned Trivia Trap.
Gene Wood was heard on countless Goodson-Todman game shows.
Burton Richardson was first heard on The Arsenio Hall Show and did some work for Mark Goodson Productions, including the last two incarnations of To Tell the Truth (one of which also had him working with O'Hurley) and the 1994 nighttime version of The Price Is Right (and some substitute work on the daytime version).
Joey Fatone made use of his vocal talents in the band *NSYNC. Like O'Hurley, he was a Dancing finalist.
Padding: Ever notice how many times the contestants bleat, "GOOD ANSWER" no matter how idiotic the response might be?
Screwed by the Network: Dawson '94 suffered from frequent pre-emptions because of the O.J. Simpson murder trial.
Throw It In: On the Ray Combs version, there were lights just off-camera that indicated the number of strikes a team had on any given question. For one set of episodes, the lights malfunctioned, so the team members were given "strike" graphics on sticks, which they would hold up any time they got a strike.
Troubled Production: Richard Dawson was constantly at odds with both Mark Goodson and show producer Howard Felsher, even barring the latter from the set. Goodson once remarked that Dawson gave him "tsoris" (Yiddish for "trouble").
In a 2011 interview, Richard Dawson said that William Shatner had gotten a crack.
On the newsgroup alt.tv.game-shows, Geoff Edwardsconfirmed that he had been tapped to host the original Feud, but declined because at the time, he had a deal pending with Bob Stewart for what became Shoot for the Stars on NBC. Jack Narz was supposedly in the running at one point as well.
Joe Namath tried out for the revival that ended up being hosted by Ray Combs.
Dolly Parton did a pilot for what ended up being the 1999 revival, but didn't make the cut.
