Ghost Hunters

The program featured Jason Hawes and Grant Wilson, who founded The Atlantic Paranormal Society (TAPS) team of paranormal investigators to investigate places that are reported to be haunted. The two worked as plumbers for Roto-Rooter while moonlighting as paranormal investigators at night. For the 12th and 13th seasons, the revived show featured Wilson and a new investigatory team that had no discernible connection to TAPS, although the series still maintained the same format and producers and referenced past episodes. For the fourteenth season, Hawes and the previous TAPS incarnation from 2016 returned, while Wilson and the new team were not featured.

The series, initially produced for 10 episodes as a docu-soap, had later episodes shift to a more documentary focus. Ghost Hunters episodes feature the team going to reportedly haunted locations across the United States, with some investigations in Ireland, the United Kingdom, and Canada in earlier seasons. The latter concept led to the show's first spin-off, Ghost Hunters International, in 2008, which often featured Ghost Hunters investigators in lead and guest roles, including Hawes and Wilson. A second spin-off, Ghost Hunters Academy (2009–10), had TAPS members Dave Tango and Steve Gonsalves training prospective investigators in a competitive format. Additionally, annual Halloween specials were broadcast live from 2005 to 2011 and featured celebrity guests and interactivity.

The series popularized paranormal reality television and ghost hunting, and some members of the show have moved on to feature in their own television programs.
