A meme consists of any unit of cultural information, such as a practice or idea, that gets transmitted verbally or by repeated action from one mind to another. Examples include thoughts, ideas, theories, practices, habits, songs, dances and moods and terms such as race, culture, and ethnicity. Memes propagate themselves and can move through a "culture" in a manner similar to the behavior of a virus.
At its most basic, an Internet meme is simply the propagation of a digital file or hyperlink from one person to others using methods available through the Internet (for example, email, blogs, social networking sites, instant messaging, etc.). The content often consists of a saying or joke, a rumor, an altered or original image, a complete website, a video clip or animation, or an offbeat news story, among many other possibilities. An Internet meme may stay the same or may evolve over time, by chance or through commentary, imitations, and parody versions, or even by collecting news accounts about itself. Internet memes have a tendency to evolve and spread extremely quickly, sometimes going in and out of popularity in a matter of days. They are spread organically, voluntarily, peer to peer, rather than by trickery, compulsion, predetermined path, or completely automated means.[2]
The term may refer to the content that spreads from user to user, the idea behind the content, or the phenomenon of its spread. Internet memes have been seen as a form of art.[3] There exist websites that collect and popularize Internet memes as well as sites devoted to the spread of specific Internet memes. The term is generally not applied to content or web services that are seen as legitimate, useful, and non-faddish, or that spread through organized publishing and distribution channels. Thus, serious news stories, videogames, web services, songs by established musical groups, or the like are usually not called Internet memes.
