The Talk Show ("Chat Show" in the UK) genre encompasses a number of different formats, but all talk shows share certain characteristics:

* Talk shows are (almost) exclusively {{nonfiction}}.
* Talk shows feature a guest or guests who are invited on a per-episode basis to discuss topics with permanent hosts.
* All talk shows are ephemeral in that they are created, shown, and then discarded or shelved. Except in rare circumstances or ''Best of...'' compilations, reruns are not shown.

'''Talk Show Formats'''

Most talk shows follow one of a number of standard formats:

#'''Morning News Talk Show:''' Light news, commentary, and fluff pieces. Examples: ''[[Series/{{Today}} The Today Show]]'', ''Good Morning America''.
#'''News Talk Show:''' Pundits arguing. ''Series/MeetThePress'' is the [[LongRunners longest-running]] example, as well as the longest running talk show, and the longest running TV show ''period''. (''Series/GuidingLight'' had 8 more years than ''Series/MeetThePress'' on radio, but 4-5 less on TV.)
#'''Pundit Show:''' A News Talk Show with only one host. Generally self-aggrandizing, highly politicized and full of vitriol and/or [[ConspiracyTheorist conspiracy theories]]. Often supported with a companion series on AM {{radio}} (if the radio show isn't the main draw in the first place) and a blog. The radio ones usually Phone-In Shows, as well. Examples: ''The O'Reilly Factor'', ''[[Creator/RushLimbaugh The Rush Limbaugh Show]]'', ''Hardball'' (with Chris Matthews), ''Series/CountdownWithKeithOlbermann'', ''Big Idea with Donny Deutsche'', ''Series/TheColbertReport'' (parody). A British version is ''The Jeremy Vine Show'', a long-running lunchtime debate-and-music show on BBC Radio Two. Vine inherited a slot formerly presented by veteran host Sir Jimmy Young. Topical political controversies are debtated and held open to the public for comment, but unlike US radio equivalents, the show is either hampered (or improved) by a strict legal requirement for political impartiality.
#'''Daytime Talk Show:''' These shows typically feature celebrities and/or ordinary people who showcase [[PointAndLaughShow scandal or dysfunctionality]]. Examples: ''Series/TheJerrySpringerShow'' (scandal), ''Live! With Kelly & Michael''[[note]]many previous names, most notably ''Live! With Regis & Kathie Lee'' and ''Live! With Regis & Kelly'' (the same Kelly)[[/note]] (celebrities), ''Series/TheOprahWinfreyShow'' (either or both). Pioneered by Phil Donahue. ''Series/DoctorPhil'' fits here, with the twist that he attempts to use psychology to help the dysfunctional people. ''[[Series/TheTalk Loose Women]]'' is a British daytime variety based on American show ''The Talk'', presented by a panel of rather opinionated professional women drawn from all areas of celebrity: journalists (Janet Street-Porter), singers (Jayne [=McDonald=], Colleen Nolan), actresses (Denise Welch) etc.
#'''Late Night Talk Show:''' Current events, comedy, and celebrity guests, such as ''Series/TheTonightShow'', ''Series/LateNight'', ''Series/TheLateShow'', ''Series/TheLateLateShow'', etc. Often a limited form of the VarietyShow, typically featuring a house band -- which is usually used to cut to commercial, and rarely shown in its entirety. Musical acts often perform a single song as the last segment of most shows. In the 70s, such shows as ''Dinah Shore'' and ''The Mike Douglas Show'' aired afternoons, a trend that saw a slight resurgence in the mid 90s.
#'''Phone-In Talk Show:''' Most common in radio, this type of show has the host(s) engaging in conversation with listeners who call in by telephone. A lot of these double as/are linked to Pundit Shows: besides Limbaugh, O'Reilly, Hannity, and [[Radio/GlennBeck Beck]], all have phone-in radio shows, as did [[Series/TheRachelMaddowShow Rachel Maddow]] before she [[SoundToScreenAdaptation hopped to TV]]. Other than those, Creator/{{NPR}} puts forward a number of phone-in shows that double as News Talk (''Talk of the Nation'' and ''The Diane Rehm Show'' being the ones syndicated nationwide); they also do ''Radio/CarTalk''. Commercial radio has a plethora of these, as well; the one that sticks in a lot of people's memories, however, is ''Radio/CoastToCoastAM,'' a talk show about the paranormal that generally airs in the wee hours of the morning.
#'''Spoof Talk Show:''' Does what it says on the tin. Examples: ''WesternAnimation/SpaceGhostCoastToCoast'', ''Series/KnowingMeKnowingYouWithAlanPartridge'', ''Series/ManToManWithDeanLearner'', ''Series/FernwoodTonight''.
#'''Sports Talk Show:''' Very similar to the News Talk Show, except that it's all about [[ExactlyWhatItSaysOnTheTin sports]]. One famous example is ''Sports Desk''. Much of Creator/{{ESPN}}'s fare as of 2018 qualifies here as well, as does Fox Sports which has a good bit of [[ChannelHop former ESPN talent]] now.
