62. Billy Mays
Mentioned on 4chan in 2007, the late infomercial king became synonymous with talking in all caps and was known for his kitschy catchphrases. In addition to tribute videos, remixes, parodies and images, there are four fan sites and several Facebook pages devoted to Mays. When he died in 2009 Digg declared ALL CAPS DAY, an event later added to Urban Dictionary.
