I've heard a few peeps this month there is a small possibility that GSN is seeking interest (but nothing is set in stone at all) about a potential revival of NBC's Deal or No Deal, FOX's Are You Smarter than a 5th Grader? or Chain Reaction.
All three shows have worked wonders in reruns for GSN. Deal or No Deal was the highest rated show on GSN consistently in 2009 and 2010 and continued moderate success into mid-2012. Deal or No Deal has since aired on the network twice in Christmas week marathons. Deal or No Deal lasted on NBC for four seasons from 2005 to 2009 and in syndication through 2010.
Deal or No Deal revival possibility: Slim to none. If GSN could have revived Deal, they would have done it by now. A GSN Deal revival would be significantly cheaper and without the models, I predict. Note that there was an all day Deal or No Deal marathon Christmas Eve this past year (December 24, 2013) where the previous year there was an NBC Minute to Win It revival also on Christmas Eve. A month later, it was announced that GSN would revive Minute. No wonder why I've heard something has been stirring.
Are You Smarter than a 5th Grader? was a hit for FOX from 2007 to 2009 then went into syndication from 2009 to 2011. 5th Grader provided GSN some of its best numbers in 2012 and 2013, the time it reran on GSN Sunday nights and weekday afternoons.
5th Grader revival possibility: Decent. Well, in my book. This would be something that GSN could easily tie-in with The Chase or American Bible Challenge and I don't think that coming up with a new gameplay would be too difficult.
Chain Reaction has been solid for GSN since 2006. Chain Reaction may have only had two seasons for its GSN revival but since the end of new episodes in 2007, Chain Reaction has held some of the network's highest numbers in only mid-afternoons.
Chain Reaction revival possibility: Higher than anything else. If GSN has to revive something, Chain Reaction has been a ratings glue for afternoon, giving other shows around it better ratings too. GSN only produced 130 episodes in their first revival and I think eight years later it's time for a second go-around. GSN taking the 2000's version off the schedule may give the show a rest where viewers miss it, then they could launch a new version.
Who really knows, this is GSN. They could revive Card Sharks or 1 vs. 100 again for all I know.
