Snopes.com

The Snopes.com web site was founded by David Mikkelson, a project begun in 1994 as an expression of his interest in researching urban legends that has since grown into the oldest and largest fact-checking site on the Internet — one widely regarded by journalists, folklorists, and laypersons alike as one of the world’s essential resources.

Snopes.com is routinely included in annual “Best of the Web” lists and has been the recipient of two Webby awards.
