Zak Bagans

In 2004, Bagans teamed up with Nick Groff and Aaron Goodwin to produce a documentary-style film called Ghost Adventures. The film aired on the SciFi Channel in 2007. A successor series premiered in 2008 on the Travel Channel and has aired for 19 seasons as of 2019. The show has been accused of fakery.[1]

From 2014 to 2016, Bagans helmed a spin-off series titled Ghost Adventures: Aftershocks, which focused on changes to people's lives after prior Ghost Adventures investigations.

On 2 April 2016, Deadly Possessions premieried on the Travel Channel; the show featured Bagans finding items for a prospective "haunted museum" in Las Vegas, Nevada. The museum opened to the public in October 2017. It consists of 33 rooms with various artifacts on display. Visitors are given guided tours of the rooms. Some of the items on display include Bela Lugosi's mirror, the Dybbuk box, Peggy the Doll, and Jack Kevorkian's "Death Van".[2] A Celebrity Deaths room contains artifacts associated with dead celebrities.[3]

All visitors must sign waivers before entering indemnifying the museum against “spiritual or paranormal interactions”. On 27 May 2019, an exhibit featuring a rocking chair from The Devil in Connecticut alleged demon possession case was shut down briefly due to a visitor fainting. The exhibit reopened on 7 June.[4]

Some of the claims attached to the artifacts have been criticised. Both the Lugosi mirror and Captain Smith mirror kept in the museum have been shown to have dubious provenance.[5][6]

Bagans co-wrote a book with author Kelly Crigger titled Dark World: Into the Shadows with the Lead Investigator of the Ghost Adventures Crew. On September 23, 2011, the book debuted on The New York Times Best Seller list at No. 18.[7]

In December, 2019, Bagans published the book Ghost-Hunting For Dummies. The book 'outlining the history of ghost-hunting, including true accounts and stories from Bagans’ famous cases and investigations, and explains how anyone can get started in investigating the supernatural.".[8] Some of the text in the book appears to have been plagiarized from other works, including those of Bill Reap, Troy Taylor, Steve Higgins, and Joe Nickell.[9] Troy Taylor has stated that Bagans and he worked together on researching material for the book. But Taylor also says that Bagans did not have permission to use his original material in the book and that he had received "a substantial payment" from Bagans in a settlement.[10] Writing for Skeptical Inquirer magazine, paranormal investigator Kenneth Biddle observes that throughout much of the book, Bagans displays a strong bias against skeptics and scientists, claiming he understands scientific concepts better than professional scientists. For example, while relating why he believes human consciousness can exist outside of the body, Bagans mentions Albert Einstein’s well-known quote, “Energy cannot be created or destroyed; it can only be changed from one form to another.” He wonders why he can see that this supports survival of consciousness beyond death but scientists cannot. However the conservation of energy simply means that the energy contained in the human body is converted into heat, into energy in the bodies of animals, plants and bacteria which consume it and in the case of cremation, into light. There are some worthwhile pieces of advice in the book, for instance in Chapter 15 Bagans covers several ways to research the history of a location by searching through old newspapers, old maps, vintage photographs, building permits, and more. But he still gets facts wrong in this book, for instance attributing the origin of the idea for the movie Ghostbusters to Harold Ramis, when it was Dan Aykroyd who wrote the original script, inspired by an article he read in The Journal of the American Society for Psychical Research.[9]
