The advent of the Internet has facilitated the proliferation of urban legends. At the same time, however, it has allowed more efficient investigation of this social phenomenon.
Discussing, tracking, and analyzing urban legends has become a popular pursuit. It is the topic of the Usenet newsgroup, alt.folklore.urban, and several web sites, most notably snopes.com.
The United States Department of Energy had a service called Hoaxbusters that dealt with all sorts of computer-distributed hoaxes and legends. This service has since been discontinued.
Television shows such as Urban Legends, Beyond Belief: Fact or Fiction, and later Mostly True Stories: Urban Legends Revealed feature re-enactments of urban legends detailing the accounts of the tales and (typically) later in the show, these programs reveal any factual basis they may have.
Since 2004 the Discovery Channel TV show MythBusters has tried to prove or disprove urban legends by attempting to test them or reproduce them using the scientific method.
