Later, during the early 1990s, the widespread adoption of telecopiers made it possible to duplicate these materials remotely. The use of a fax machine to duplicate these materials also changed the emphases of their subjects; various alarms and urban legends were propagated to distant readers over the telephone lines. This use of fax has been somewhat supplanted by email as that technology became more widely used and embedded in the culture; the sort of urban legends that once circulated by fax are now likely to appear as email hoaxes. Specific computer related alarms are the subject of virus hoaxes; email makes forwarding of texts relatively easy, and the frightening nature of the revelation makes it seem important to pass along, despite any doubts the sender might have.
