Quite possibly because of its foolproof formula. Get two teams, a host and some survey questions, and let it go.
Since it started airing in March 2012, the Harvey-hosted edition has received obscenely high ratings for the network, leading it in particular to be the second-most aired show on GSN (the first is The American Bible Challenge). Steve Harvey himself is another example.
Despite taking considerable measures against it, GSN aired three different Barker episodes of The Price Is Right offering fur coats.note November 17, 1972; June 13, 1977; 1980.
At least twice, an episode aired with all of its original (not inserted by GSN) commercials — a Bud Collyer To Tell the Truth (December 23, 1966) and a Dick Clark Pyramid (July 20, 1978).
There have also been at least two occasions of some original commercials remaining, both on Richard Dawson's Family Feud — a showing of the August 15, 1977, show left in the commercials between Fast Money and the closing segment, and a 2000 airing of a 1979 episode left in ads for Stove Top stuffing and Maxwell House coffee.
When the February 28, 1952, episode of Winner Take All was shown in September 2004, GSN accidentally showed a Station Ident (specifically, WNBT in New York) for a few seconds.
Many episodes have been screwed up massively by the time-compression machine (resulting in everyone speaking like the Micro Machines man for a few seconds), incorrect cuts to commercial, or glitching during the credits pushback.
Hey, It's That Guy!: Many of GSN's original programs have been helmed by experienced hosts, such as Chuck Woolery, Bob Goen, Mark L. Walberg, and Marc Summers.
Hey, It's That Voice!: Veteran announcer Gene Wood's last regular job was as a staff announcer for GSN. He retired in the late 1990s.
Missing Episode: Some episodes of Match Game and The Hollywood Squares were taken out of rerun packages because they contained racial slurs. At least one Match Game episode was pulled because it had tape errors, and still more are unaired by the network due to failed celebrity clearances.
Screwed by the Network: Most, if not all, of GSN's originals got shuffled around repeatedly within the schedule for no reason, and most were canned after two seasons at most. Lingo was the hardest hit in this regard, but it still managed to last five seasons. Not to mention the fact that GSN rarely, if ever, announced that a show was truly canceled.
