Some fun facts from Global Politician:
There are more than 186,600 Web sites dedicated to conspiracy theories in Google's database of 3 billion pages. The "conspiracy theories" category in the Open Directory Project, a Web directory edited by volunteers, contains hundreds of entries.
There are 1077 titles about conspiracies listed in Amazon and another 12078 in its individually-operated ZShops. A new (1996) edition of the century-old anti-Semitic propaganda pamphlet faked by the Czarist secret service, "Protocols of the Learned Elders of Zion", is available through Amazon. Its sales rank is a respectable 64,000 - out of more than 2 million titles stocked by the online bookseller.
In a disclaimer, Amazon states:
"The Protocols of the Learned Elders of Zion is classified under "controversial knowledge" in our store, along with books about UFOs, demonic possession, and all manner of conspiracy theories."
Yet, cinema and TV did more to propagate modern nightmares than all the books combined. The Internet is starting to have a similar impact compounded by its networking capabilities and by its environment of simulated reality - "cyberspace". In his tome, "Enemies Within: The Culture of Conspiracy in Modern America", Robert Alan Goldberg comes close to regarding the paranoid mode of thinking as a manifestation of mainstream American culture.
According to the Internet Movie Database, the first 50 all time hits include at least one "straight" conspiracy theory movie (in the 13th place) - "Men in Black" with $587 million in box office receipts. JFK (in the 193rd place) grossed another $205 million. At least ten other films among the first 50 revolve around a conspiracy theory disguised as science fiction or fantasy. "The Matrix" - in the 28th place - took in $456 million. "The Fugitive" closes the list with $357 million. This is not counting "serial" movies such as James Bond, the reification of paranoia shaken and stirred.
