He has been featured on various television shows including the History Channel's Decoded and America's Book of Secrets; Conspiracy Theory with Jesse Ventura, Secret Societies of Hollywood on E!

Mark Dice is the author of several popular books on secret societies and conspiracies, including The Illuminati: Facts & Fiction, Big Brother: The Orwellian Nightmare Come True, The New World Order: Facts & Fiction, Inside the Illuminati, and Illuminati in the Music Industry. While much of Mark's work confirms the existence of secret government programs and cover-ups, he is also dedicated to debunking conspiracy theories and hoaxes and separating the facts from the fiction; hence the "Facts & Fiction" subtitle for several of his books. He has a bachelor's degree in communication from California State University.
