Here’s an infographic by Online University that does a good job of describing Internet memes and the sites that host them. A meme is a cultural idea that self-replicates and spreads among people, and an online meme can appear in many forms — a video, a catchphrase, a Web site, a joke, an image, a parody, etc.
The infographic presents a great mix of some of the funniest, most popular memes in Internet history. Ever wondered about the origins of the Dancing Baby or the Dancing Hamster? What about LOLCats, Rickrolls, or the Star Wars Kid? Find out below about these and other funny videos and parodies.
