This is a
list of phenomena specific to the
Internet, such as
popular themes and catchphrases, images,
viral videos and more. Such fads and sensations grow rapidly on the Internet because its instant communication facilitates
word of mouth. In the early days of the Internet, phenomena were primarily spread via
email or
Usenet discussion communities. Today, many of these phenomena are also spread via popular, user-based or
social networking web sites, including
4chan,
Newgrounds,
Reddit,
Facebook,
Fark,
Flickr,
Myspace,
Slashdot,
Something Awful,
YouTube, or
YTMND. Search engines, such as
Google,
Yahoo, or
Bing may also amplify the propagation of these phenomena.
