New Order one world government, Zionist and Jewish cabals, Catholic, black, yellow, or red subversion, the machinations attributed to the freemasons and the illuminati - all flourished yet again from the 1970's onwards. Paranoid speculations reached frenzied nadirs following the deaths of celebrities, such as "Princess Di".

Books like "The Da Vinci Code" (which deals with an improbable Catholic conspiracy to erase from history the true facts about the fate of Jesus) sell millions of copies worldwide.

Tony Blair, Britain's ever righteous prime minister denounced the "Diana Death Industry". He was referring to the tomes and films which exploited the wild rumors surrounding the fatal car crash in Paris in 1997. The Princess, her boyfriend Dodi al-Fayed, heir to a fortune, as well as their allegedly inebriated driver were killed in the accident.

Among the exploiters were "The Times" of London which promptly published a serialized book by Time magazine reports. Britain's TV networks, led by Live TV, capitalized on comments made by al-Fayed's father to the "Mirror" alleging foul play.

A 12 months subscription to "Fortean Times" costs c. $45.

With a circulation of 60,000, the magazine was able to spin off "Fortean Television" - a TV show on Britain's Channel Four. Its reputation was further enhanced when it was credited with inspiring the TV hit series X-Files and The Sixth Sense. "Lobster Magazine" - a bi-annual publication - is more modest at $15 a year. It is far more "academic" looking and it sells CD ROM compilations of its articles at between $80 (for individuals) and $160 (for institutions and organizations) a piece. It also makes back copies of its issues available.

Its editor, Robin Ramsay, said in a lecture delivered to the "Unconvention 96", organized by the "Fortean Times": "Conspiracy theories certainly are sexy at the moment ...
