There are many popular channels on YouTube, and many relatively unknown folk have made a name for themselves on the Google-owned viral video hunt. With that said, few have managed to generate the hype of Korean rapper / pop star PSY, whose "Gangnam Style" song has eclipsed anything the web has ever seen. Although first uploaded in September, it didn't really go viral until late August-early September, and has accumulated almost half a billion views on the way to becoming the fourth most watched - and most liked - clip in YouTube's history.
