A meme is "an idea, behavior, or style that spreads from person to person within a culture". An Internet meme may take the form of an image, hyperlink, video, picture, website, or hashtag. It may be just a word or phrase, including an intentional misspelling. These small movements tend to spread from person to person via social networks, blogs, direct email, or news sources. They may relate to various existing Internet cultures or subcultures, often created or spread on sites such as 4chan, Reddit and numerous others in our time, or by Usenet boards and other such early-internet communications facilities. Fads and sensations tend to grow rapidly on the Internet, because the instant communication facilitates word-of-mouth transmission. History In the early days of the Internet, such content was primarily spread via email or Usenet discussion communities.
