TV Tropes
TV Tropes (stylized as TVTropes as of February 2016) is a wiki that collects and expands descriptions and examples on various conventions and devices (tropes) found within creative works. Since its establishment in 2004, the site has shifted focus from only television and film tropes to cover those in other types of media such as literature, comics, video games, advertisements, and toys. The nature of the site as commentary on pop culture and fiction has attracted attention and critique from several web personalities and blogs.
The content of the site was published as free content from April 2008. TV Tropes changed its license on July 2012 to only allow noncommercial distribution of its content while continuing to host the prior submissions under the new license.

Informality
TV Tropes initially focused on the television show Buffy the Vampire Slayer and has since increased its scope to include thousands of other series, films, novels, plays, professional wrestling, video games, anime, manga, comic strips and books, fan fiction, and many other subjects, including Internet works such as Wikipedia, which is referred to in-wiki as "The Other Wiki". It has also used its informal style to describe topics such as science, philosophy, politics, and history under its Useful Notes section. TV Tropes does not have notability standards for the works it covers.
