Digg is a social news website started out as an experiment in November 2004 by Kevin Rose and Jay Adelson. Kevin Rose’s friend David Prager originally wanted to call the site “Diggnation”, but Kevin wanted a simpler name. He chose the name “Digg”, because users are able to “dig” stories, out of those submitted, up to the front page. The site was called “Digg” instead of “Dig” because the domain name ‘dig.com’ was previously registered, by Walt Disney Internet Group. “Diggnation” would eventually be used as the title of Kevin Rose and Alex Albrecht’s weekly podcast discussing popular stories from Digg.
