-> ''When people face what nothing in their past has prepared them for they grope for words to name the unknown, even when they can neither define nor understand it...The keyword was the small preposition, "after," generally used in its latinate form "post" as a prefix...to mark out the mental territory of twentiety-century life. The world...became post-industrial, post-imperial, post-modern, post-structuralist, post-Marxist, post-Gutenburg, or whatever.''
-->-- '''Eric Hobsbawm''', ''The Age of Extremes''

In academia, adding the prefix "post" to a movement, theory, genre, etc is quite common. The best way to describe the meaning of "post" in this context is to see that "post" is a synonym for "beyond", building on the innovations, theories, style, etc of the original in such a way as to take it beyond what the original was, creating a new theory, genre, whatever, in the process. See Also EvolvingTrope.

Often subverted in popculture. Usually when someone is being called a "Post-something", it amounts to [[TheWarOnStraw Strawman]].
* PostModernism, (which refers to a large number of loosely connected movements, including, but not limited to the trope used here) gets its name because its goal was/is to move beyond the movement of modernism. An excellent definition of postmodernism (insofar as postmodernism can be defined) is, "an interruption of the modern mythological form."
** And in recent years, there's been a growing movement towards what has been called "Post-Post Modernism", which is a rejection of PostModernism in the same way PostModernism is a rejection of Modernism.
* Bands such as the Music/FooFighters and Music/{{Creed}} have been called "PostGrunge" because they borrow various elements of classic grunge, while at the same time experimenting with new elements.
** There's also "PostRock", "PostPunk" and "Post-Metal", just to add more genres. Oh, and "Post-Hardcore", too.
** Don't forget Post-Britpop, i.e. Music/{{Coldplay}}.
** [[http://www.last.fm/tag/post-whatever Post-whatever]].
* Post-Disco, which includes most modern pop music. Hip Hop, most electronica, and progressive R&B just to name a few.
* Wiki/TheOtherWiki once had a humorous example in an article named "Post Gangsta Rap", sadly, said article no longer exists, so we don't get an explanation.
* PostCyberpunk tries to move beyond the cynicism and hopelessness of CyberPunk in various ways, such as giving hope for the future (Film/TheMatrix Trilogy does this with a messiah figure), showing the upside of technological progress (works that focus entirely on the bright side of cyber-technologies, and don't also show the potential downsides, are called "cyber prep") or by parodying or deconstructing Cyber punk tropes (''Literature/SnowCrash'' and ''ComicBook/{{Transmetropolitan}}'' come to mind.)
* {{Reconstruction}} could be said to be "Post-{{Deconstruction}}", in that it tries to move the genre beyond the criticism of the deconstruction, while at the same time accepting said criticism.
* The UrExample is Post-Impressionism, a term used by art historians to describe artists like Creator/VincentVanGogh, Creator/HenriDeToulouseLautrec, or Paul Gauguin, who built upon the innovations of the Impressionists and took painting to new styles of expression. Not so much a cohesive art movement as a bunch of loosely-affiliated, like-minded yet fiercely independent artists.
* Many developed nations are said to have "post-industrial" economies, since the service and finance sectors are more important than the industrial sector.
* Similarly, certain kinds of products are considered to be Post-Scarcity goods. An excellent example is computer software, which, once written, can be infinitely duplicated at virtually zero cost.
* Though the term was first coined in 1992, after the election of UsefulNotes/DonaldTrump, the term post-truth gained a lot of traction. Referring to constant repeating of BlatantLies even after said lies have been debunked by appealing to emotion. The terms "Fake News" and "Alternative Facts" stem from this idea.
