John Titor/Origin

Origin
John Titor is the name used on several bulletin boards during 2000 and 2001 by a poster claiming to be a time traveler from 2036.

In these posts, Titor made numerous predictions about events in the near future, a number of them vague and some quite specific, starting with events in 2004. He described a drastically changed future in which the United States had broken into five smaller regions, the environment and infrastructure had been devastated by a nuclear attack, and most other world powers had been destroyed.

To date, the story has been retold on numerous web sites, in a book, in a play, and the Japanese visual novel/anime Steins;Gate. Titor has also been discussed occasionally on the nationally syndicated radio show Coast to Coast AM.
