A trope of {{Game Show}}s, {{Magazine Show}}s and similar. This is where the host or other regular "character" in such a show manages to add far more to a show than would be expected; expect a ton of PeripheryDemographic in any show that manages to evoke this. Related to EnsembleDarkHorse, but separate as it tends to involve the closest things such shows have to a central character (although it can sometimes involve a side star).

If the star is replaced by someone else ([[GuestHost even temporarily]]) expect invocations of ReplacementScrappy, TheyChangedItNowItSucks and FanonDiscontinuity (as close as a nonfiction show can get anyway).



[[folder: Game Shows]]
* ''Series/CashCab'' is literally driven by Ben Bailey.
** Or Adam Growe in Canada.
* Roy Walker of ''Series/CatchPhrase''. When he left the show, the show's popularity left with him and the new host found himself with a broken leg mere seconds into his first episode, the show itself was axed three years later.
* Richard O'Brien on ''Series/TheCrystalMaze''.
** Who was replaced by Ed Tudor-Pole for the last two series, who did a good job, but was no O'Brian.
* ''Series/DealOrNoDeal'' wouldn't be half as much fun without Howie Mandel. Or Noel Edmonds. Or Andrew O'Keefe.
* Marc Summers of Creator/{{Nickelodeon}}'s ''[[Series/DoubleDare1986 Double Dare]]''.
** Possibly made more awesome because Summers suffered from Obsessive Compulsive Disorder and no one at the time would've guessed even though ''Double Dare'' was not what one would call a, erm, clean game show...
** It was even worse with his later show ''[[Series/WhatWouldYouDoNickelodeon What Would You Do?]]'' which was ''just'' as messy but had no set format. Furthermore in the last segment of the show (where they would put cards with various stunts on people's heads and they would have to either do the stunt or visit the various pie contraptions) they always gave Marc the the messiest thing they could think of. There's a reason why they usually ran out of time before they got to him...
* Richard Dawson, and later Ray Combs, both were immensely popular hosts on ''Series/FamilyFeud'', and each brought a lot to the program. Successors Louie Anderson, Richard Karn, and John O'Hurley, on the other hand, provided excellent foils, as the show failed to recapture its former popularity with the three hosts. Come Steve Harvey's turn in 2010, however, coinciding with a raunchier change of tone with the survey questions and answers, and the show is now the ''second-highest program in syndication''.
* ''The Golden Shot'' was hugely popular when Creator/BobMonkhouse was hosting it, but nobody else could ever get it to work.
* ''Series/NickelodeonGUTS'' wouldn't be the same without Mike O'Malley and Moira Quirk, and it really showed with ''My Family's Got GUTS'', where [[ReplacementScrappy Ben Lyons]] and Asha Kuerten replaced them. Though the former duo weren't working for Nickelodeon at the time, and Asha was praised by some fans for equalling Moira.
* Robert Llewellyn on ''Series/ScrapheapChallenge''.
* For most people, ''Series/{{Jeopardy}}'' just wouldn't be the same without Alex Trebek (at least since it was {{Uncanceled}} in TheEighties).
* ''Series/{{Knightmare}}'' features Hugo Myatt presenting ''in character'' as dungeon master Tregard.
* [[Creator/DeeBradleyBaker Olmec]] of ''Series/LegendsOfTheHiddenTemple'', much more so than the actual (rather mediocre) MC, Kirk Fogg. The producers acknowledged this by giving the job of reading the {{Rules Spiel}}s for the various challenges to Olmec rather than Fogg starting with the second series.[[note]] Which is a bit hard on Fogg, who has publicly stated that he was shoved in front of the camera with little to no preparation, and the rules spiels were written on cue cards he was seeing for the first time; the fact that the punctuation on the cards was haphazard at best resulted in equally haphazard line readings.[[/note]]
* The '70s revival of ''Series/MatchGame'' was all over this trope, taking what could have been a boring parlor game and putting it into the hands of six celebrities and emcee Gene Rayburn, all of whom were much more interesting to watch with their antics than the actual game they were playing. Even better were episodes to be shown later in the week (apparently, the shows for a week were all shot on one day, and somewhere around Wednesday's show everyone took a lunch break... for the celebrity panel, there were often three, four or five martini lunch breaks, and it showed through the increasingly anarchic behavior of those installments...)
** The Comedy Network reboot definitely gets a boost from both host Darrin Rose (who, impressively, doubles as announcer), as well as Debra Digiovanni and Sean Cullen, the only permanent panelists.
* No one but Peter Tomarken could host ''Series/PressYourLuck'', but Todd Newton came pretty damn close with ''Series/{{Whammy}}!''.
** Peter Tomarken almost hosted ''Whammy!''. Creator/{{GSN}} filmed two pilots: one featuring Peter Tomarken and the other featuring Todd Newton. Just think about WhatCouldHaveBeen.
* ''Series/ThePriceIsRight''. The seasons with Bob Barker were carried by him and has a very different feel than the seasons with Drew Carey. The version with a third host is almost unknown to people who have not seen it or read this wiki.
* The NBC version of ''Series/TheSingingBee'' had some mediocre success with host [[Music/{{NSYNC}} Joey Fatone]]. However, when the show [[ChannelHop channel hopped]] to CMT, they hired stand up comic Melissa Peterman. It's been more successful, notably since Peterman's charisma is able to cover when a contestant is nervous, too quiet, or simply dull.
* Jenny [=McCarthy=] and ''Series/SingledOut''. The show only lasted a season and a half after her departure, despite being replaced by Carmen Electra.
* ''Series/TakeshisCastle''. Watching people falling in mud and injuring themselves: funny. Watching them do it to Craig Charles' commentary: hysterical.
* Creator/{{ABC}}'s ''[[Series/{{Wipeout2008}} Wipeout]]'': John Henson and John Anderson's commentary is as funny as watching the contestants trip and fall. And it is now clear that Jill Wagner as the interviewer was seriously underestimated, as her replacement isn't nearly as good.
** ''Total Wipeout'' (the UK version, airing on Creator/{{BBC}}) itself may count too. It's hosted by [[Series/TopGear Richard Hammond]], and [[DeadpanSnarker his snark]] makes watching the contestants fail miserably even funnier.
** The Swedish ''Wipeout'' also would be nowhere as good without its hilarious hosts.
* In Australia, there was practically a national outcry (among people of a certain age group, anyway) when "Baby" John Burgess was dropped as host of ''Series/WheelOfFortune''.
** Stateside, Pat Sajak's sharp wit and overall charisma and the ridiculous popularity of Vanna White have played a large part in what made ''Wheel'' the 30+ year success that it is. Chuck Woolery and Susan Stafford also have their share of fans.
* Regis Philbin for ''Series/WhoWantsToBeAMillionaire'', in spite of the show having lasted almost four times as long with successors Meredith Vieira and Cedric the Entertainer.
** Also applies to the German version. The host, Günther Jauch, is probably the most popular person in this country.
** And also Chris Tarrant makes the British version of the show what it is. The guy knows a heck of a lot, and never gives anything away with his [[CatchPhrase "Is that your final answer?"]]
* ''[[Series/WinBenSteinsMoney Win Ben Stein's Money]]'' was carried by the father/son-like relationship between Ben Stein and Jimmy Kimmel. When Kimmel left, it went downhill in a hurry.
* No one ever, ''ever'', tuned into the original ''Series/YouBetYourLife'' for game value; they tuned in to watch [[Creator/MarxBrothers Groucho Marx]] be, well, [[DeadpanSnarker Groucho Marx]].
* Just about any show hosted by Creator/BillCullen that wasn't the original ''Price is Right''. Most of the shows he was associated with went off the air in a year or less (''Series/WinningStreak'', ''Series/HotPotato'', ''Series/ChildsPlay'', etc.) but he was such a phenomenal host that he made even the most mediocre game format watchable. It should be noted, however, that many of the shows that he hosted that did end up failing generally ended up doing so as a result of getting ScrewedByTheNetwork, not because of any formatting flaws. The lone exception, ''Series/{{Blockbusters}}'' (which also qualifies), got a ''much'' longer run in the UK, but had a much ''shorter'' run a second time in the US (with successor Bill Rafferty).
* The German ''Wetten Dass...'' was carried by the ''second'' host, Thomas Gottschalk. In the zero's, he was replaced with an other host, which let the ratings drop dramatically. He returned, and everything was well again.
** After a dramatic incident [[http://www.youtube.com/watch?v=Zp0rVNahOtE (see it here),]] he left the show for good. They took lessons from the last time, and changed a lot about the show, to prevent his successor from becoming a ReplacementScrappy.
** Which is precisely what happened anyway. It took Gottschalk's successor less than a year to ruin the show in the eyes of most viewers and the critics.
* ''Series/WhereInTheWorldIsCarmenSandiego'' was made memorable entirely due to its terrific cast: Greg Lee, Lynne Thigpen, and, of course, Rockapella. Only Thigpen carried over to SequelSeries ''Series/WhereInTimeIsCarmenSandiego'', which is the main reason that show is widely considered inferior.
* ''Series/FriendOrFoe'' just wouldn't have been the same without Kennedy's [[DeadpanSnarker snarking]] at anyone who went Foe, as repeatedly proven by numerous other game shows which have since used the same prisoner's dilemma gimmick, every last one of which has fallen flat on their faces.
* ''Series/TheChase'' wouldn't be anywhere near as entertaining without the Chasers themselves and their own comments and quips about the contestants and show itself. Or presenter Bradley Walsh and his own jokes and comments (and the tendency to burst into laughter or such like whenever someone says anything entertaining). This is also likely why the US version didn't try and find a US equivalent quiz genius and simply hired Mark Labbett from the UK version to act as the Chaser on that version of the show as well.
** It's also likely why the Australian one brought over Anne Hegerty as one of the Chasers, and then brought in Mark Labbett a few years later.
* The various presenters of the otherwise cheap and one-shot ''Blankety-Blank'' all made the show work. Sir Radio/TerryWogan, then deadpan snarker LesDawson, and finally acid-tongued Scouse drag artist [[LilySavage Paul O'Grady]], all made a virtue of the show's legendary cheapness and the unbelievably cheap and tacky prizes the members of the public were fighting for.
* Fifteen total years, four Emmys, a slew of awesome and funny moments, and no less than three relatively unsuccessful revivals all add up to one universal game show truth: Only Creator/DickClark can host ''Series/{{Pyramid}}''.
** Unless your name is Bill Cullen (see above), whose version lasted a respectable five years alongside Clark's in the late 1970s.
** And Michael Strahan is also shaping up to be a good successor.
* Peter Marshall will always be the master of ''Series/TheHollywoodSquares''. Tom Bergeron would prove to be a close second later on.
* Allen Ludden, called "Mr. Series/{{Password}}" for a reason. The man guided the series through various network and format changes for all of two decades. His successors -- Tom Kennedy, Bert Convy, and Regis Philbin -- proved to not be quite as popular (though not without their fans).
* Not only is ''Series/LetsMakeADeal'' Monty Hall's signature series, but Hall himself is ''Deal''[='=]s signature host. Bob Hilton and Billy Bush... not so much. Hilton's version lasted one season; Bush's, '''five episodes''' (three of which aired). Hilton was actually replaced by Hall for his version's final weeks in a last-ditch attempt to save the show (which didn't work).
** Wayne Brady is rapidly proving himself as another example.
* ''Series/StrikeItLucky'' didn't last long in the US, and when it went to the UK the prizes tended to suck. But that didn't matter- people tuned into see the weird contestants and, of course, Mr. Michael Barrymore.

[[folder: Panel Shows]]
* Angus Deayton, the original chairman of ''Series/HaveIGotNewsForYou'', remains popular among fans of the show, several years after being sacked for personal indiscretions. While the rotating guest hosts have produced many popular replacements, there is still a considerable segment that wants Angus back full time.
** Meanwhile, it's nigh impossible to imagine the show without Ian Hislop (who's never missed an episode) or Paul Merton (who took the eleventh series off and has noted, as have others, that the show picked up somewhat after that little experiment).
* Humphrey Lyttelton was ''Radio/ImSorryIHaventAClue'' to such an extent that his death in 2008 and subsequent replacement by Creator/StephenFry, Rob Brydon and Jack Dee has elicited all of the complaints listed above. It's still good, but it's definitely not the ''same''.
* Nicholas Parsons, host of ''Radio/JustAMinute'', and now the last surviving original participant. Over the years, the show has seen many, many different panellists and their personal styles, but they've ''all'' [[ButtMonkey made fun of the chairman]], and he's ''always'' {{lampshaded}} it.
* Simon Amstell and/or team captains Phil Jupitus and Bill Bailey on ''Series/NeverMindTheBuzzcocks''.
** Being put to the test now that Amstell and Bailey have both left the show.
** Ten years ago, it was being carried by Jupitus, Mark Lamarr and Sean Hughes, and the thought of continuing once Lamarr and Hughes left provoked the same reaction.
* ''Series/TalkinBoutYourGeneration'' wouldn't be half as fun without Creator/ShaunMicallef. What would normally be a bland family-oriented quiz show ends up hilarious due to the Shaun's PostModern Pythonesque insanity.
* Peter Segal and Carl Kasell pretty much define ''Radio/WaitWaitDontTellMe'', so much so that Kasell still does the show even after retiring from newscasting in 2009.
* Try and imagine ''Series/{{QI}}'' without Creator/StephenFry or Alan Davies for a second. Davies once missed a show, and they left his seat empty rather than replace him.
** No need to wonder how it would be without Stephen Fry for much longer. Time will tell if Sandi Toksvig can carry it on.

[[folder:Reality Shows]]
* ''Series/TheAmazingRace'' just wouldn't be same without Phil Keoghan.
* Viewing of ''Series/AmericanIdol'' dropped drastically every time judges were replaced. When Simon left to run the American version of ''[[Series/TheXFactor X-Factor]]'' in 2016, Idol ran its final episode.
* Anderson Cooper on the first two seasons of ''Series/TheMole''. He was by far one of the funniest and most charming game show/reality show hosts out there. He also gets bonus points for being one of the only hosts witty enough to spot RealityShowGenreBlindness and tease the contestants for it. Not-so-shockingly, he's currently one of the most-respected broadcast journalists in the world.
* Jeff Probst is this for ''Series/{{Survivor}}''. For a show that loses many viewers each season due to having too similar concepts each season, many people continue watching it partly because of Probst.
** Swedish ''Expedition: Robinson'' (the original ''Survivor'') has gotten this in Paolo Roberto, who took over as host in 2009. Roberto's no-nonsense attitude (like when he chews one tribe out and basically calls them morons for not having learned how to make fire before going on the show) has quickly become a favorite for most viewers, as has his various quirks such as the way he bellows "''Köööööööööööööööööör''" (means "go") to signal the start of any competition.
** Well, the guy did [[Literature/TheMillenniumTrilogy beat the crap out of a seven foot behemoth who's immune to pain]].
* Dave Lamb carries the UK version of ''Series/ComeDineWithMe'' - and that's as a voiceover without ever appearing on screen.
* Creator/GordonRamsay may be the patron saint of this trope. What popular cooking and restaurant shows spring immediately to mind? In the US, three featuring Ramsay - Series/HellsKitchen, Series/MasterChef, and Series/KitchenNightmares - will place high on the list, and Ramsay's profanity-laden tirades followed by occasional heartwarming praise are both famous. As of 2015, [=MasterChef=] US is on its fifth season without signs of slowing down, the US version of Hell's Kitchen has an impressive 13 US seasons with a fourteenth confirmed, and Kitchen Nightmares managed a respectable 5 UK seasons and 7 US seasons before Ramsay chose to shut it down. Despite the show's success, there was no attempt to revive it with a different key chef. It's not just the US, either. Ramsay has versions of his shows in other nations, including his native England. Even non-fans will immediately recognize Ramsay's mannerisms and speech patterns. Only his flop, ''Series/HotelHell'', didn't seem to survive on Ramsay's larger-than-life persona. Say what one will about whether he is as great a chef as his reputation would suggest; he Ramsay has an amazing television presence.
* ''Series/ProjectRunway'' is heavily reliant on the personas of Heidi Klum and Tim Gunn (and maybe to a lesser degree Nina Garcia, Michael Kors and/or Zac Posen). The absence of their personalities makes the All-Stars incarnation of the show much less interesting.

* Bob Saget on ''Series/AmericasFunniestHomeVideos'' (though they try to make it seem like Tom Bergeron was always there these days...)
** The British version, ''You've been Framed'', was pretty much so-so and just cheap infill on an early Saturday evening, before the good stuff started--like the above mentioned ''Catch Phrase''. And then off-the-wall comedian [[Series/HarryHillsTVBurp Harry Hill]] took over doing the commentary and voiceovers. It's now the Harry Hill Show, with background film provided by members of the public.
* Dominic Diamond on ''Series/GamesMaster'' (also notable for Season 3 being considered along the lines of CanonDiscontinuity for him being replaced by Dexter Fletcher for that season).
* Both the Japanese and American incarnations of ''Series/IronChef'', with Chairman Kaga and the Japanese commentators/Alton Brown respectively. Gordon Elliott (in the ''IC Japan'' New York special) and Creator/WilliamShatner (the doomed ''Iron Chef USA'') have both tried to fill the host role--the former failed, the latter was damned awesome but got hamstrung by UPN's typical idiocy.
* ''Series/MythBusters'' owes most of its success to the [[OddCouple dynamic duo]] that is Adam Savage and Jamie Hyneman. (The PowerTrio of the Build Team have their own unique personalities that are also interesting to watch.) The short-lived show [[FollowTheLeader "Smash Lab"]] tried to replicate the explosions and large-scale experiments similar to ''Series/MythBusters'', but failed because the hosts weren't ''nearly'' as entertaining when constructing the giant engineering project of the week.
** The two shows had a fundemental difference as well: ''Series/MythBusters'' was about trying to prove or disprove a myth, while ''Smash Lab'' was mostly about creating solutions in search of problems.
** A show that manages to get it right, but not ''quite'' as perfect as ''Series/MythBusters'' is ''Series/TimeWarp'' as the two hosts actually knew the science behind most of what they were talking about and also had interesting personalities to help keep viewers from getting bored.
** Interestingly, the Series/MythBusters were [[EarlyInstallmentWeirdness originally]] [[ExecutiveMeddling encouraged]] to emulate the onscreen dynamics of another popular Discovery Channel show, ''Series/AmericanChopper'' (itself a prime example of this trope; the show has long since been more about family drama than anything to do with motorcycles). They eventually refused to keep acting this way, and their popularity has only waxed since.
* Joel [=McHale=] of ''Series/TheSoup''.
* Tom from Creator/CartoonNetwork's Toonami. When he was replaced with [[ReplacementScrappy TOM 4]], you just knew Toonami was in trouble.
** At least they learned from their mistake, since when Toonami was revived on Creator/AdultSwim, Tom was redesigned to be much more like the original.
* Jeremy Clarkson, James May, and Richard Hammond on ''Series/TopGear''. And The Stig, of course. Both Clarkson and May presented Old ''Top Gear'' before it was canceled, though not at the same time.
* ''Series/UnsolvedMysteries'' was never the same without Robert Stack.
* Former driver Martin Brundle's commentaries for UsefulNotes/FormulaOne racing are noted by many as being one of the main reasons to watch in many English speaking countries. He's even got his own [[http://brundleandfriends.blogspot.co.uk/ appreciation blog]].
** Brundle's case is helped that he was a former racing driver and is very insightful in how the sport runs. Not only that, he worked alongside the legendary Murray Walker, who was known for his high enthusiasm and making amusing mistakes in the heat of the moment. This meant that as Brundle wasn't a replacement for Murray, people had time to grow used to him. Played straight with James Allen and Jonathan Legard, they are accomplished commentators in their own right; but they just can't match up to Murray's personality.
* Many American ''Series/WhoseLineIsItAnyway'' fans feel this way about Drew Carey, has his interactions with Ryan and Colin were often the best part of the show. Aisha Tyler hasn't had nearly as much luck.
** Clive Anderson, the host of the British version, is also this to many fans. Several find him to be superior to both American hosts.
* ''Series/DirtyJobs'' would be at best mildly entertaining without [[DeadpanSnarker Mike]] [[SelfDeprecation Rowe]] at the helm.
* ''WesternAnimation/DragonTales'' has an in-universe example. The characters play a game of Simon Says hosted by a friendly gnome named Simon. When you get right down to it, it's really not much different from a traditional game of Simon Says, but ''boy'' does Simon work to sell it.
* It's generally accepted that, aside from the general improvement in the standards of the competitors and higher production values, the thing that really made the second season of ''Series/RobotWars'' take off was replacing Jeremy Clarkson (who was deadpan and often [[{{Jerkass}} quite rude to the contestants]]) with Creator/CraigCharles as host (it helped that, while Clarkson genuinely didn't like the show, Craig's [[LargeHam bombastic enthusiasm]] simply ''couldn't'' be faked). Whether Creator/DaraOBriain has managed to live up to Craig's legacy in the show's 2016 reboot is [[BaseBreaker a matter of some contention]].
* For a great many British viewers, the only reason to watch the Series/EurovisionSongContest was for Radio/TerryWogan's acerbic commentary, to the point where the first words uttered by replacement commentator Graham Norton when the 2009 contest began were, "I know, I miss Terry too." This did not always endear him to viewers in other countries where the competition is, if not SeriousBusiness, at least seen as something more than SnarkBait.
