It has been pointed out that Titor’s story is uncannily similar to Pat Frank's classic post-apocalyptic science fiction novel Alas, Babylon and was debunked as a hoax by an Italian TV show after running an extensive investigation. They concluded that John Titor was in fact the computer expert brother of a man by the name of Larry Haber, an advocate and owner of the commercial rights about all concerns involving John Titor.
