There are those people who find themselves fascinated with the idea of ghosts, and then there are others who need proof. The crew of Syfy’s Ghost Hunters leans toward the latter with their popular phrase, “One in three Americans believe in ghosts. Jason and Grant believe in proof.”

First airing on Syfy in 2004, the show features two plumbers, founder Jason Hawks and co-founder Grant Wilson, from Rhode Island and their team of Amy Bruni, Steve Gonsalves, Dave Tango, Adam Berry, a winner from Ghost Hunters Academy, and Maddie, the “ghost-hunting dog.” Currently in its eighth season, Ghost Hunters is the longest running Syfy reality series, according to Entertainment Weekly,

The popularity of the series quickly grew and the catchphrase most viewers recognize is “Did you hear that?”

The team has led investigations in Kentucky several times. Recently, it investigated the Buffalo Trace Distillery in Frankfort, the legendary Bobby Mack’s Nightclub in Wilder, and Waverly Hills in Louisville, which won the 2010 fan favorite site for the team to return to during their seventh season and was the site of the 2007 Ghost Hunters Live Halloween Special.

The series has also inspired two spin-offs: Ghost Hunters International and Ghost Hunters Academy. Ghost Hunters International takes the show to a new level hunting ghosts overseas. Ghost Hunters Academy takes average ghost hunter investigators and puts them through training with Steve Gonsalves and Dave Tango. The winners have become regular investigators-in-training to Ghost Hunters and Ghost Hunters International.

The team is sent to some extravagent destinations each week including Alcatraz Island, which housed the legendary Al Capone and Robert Franklin Stroud, “The Birdman of Alcatraz,” in San Francisco, and The Stanley Hotel in Estes Park, Colo., where Stephan King’s The Shining was filmed and the idea for the book came from.

The recent episode revealed one of the original team members and co-founder, Grant Wilson, will leave the series May 16. According to Entertainment Weekly, Wilson is leaving the series for personal reasons.

The series returns to Syfy April 11. The show has one episode aired on Wednesday nights at 9 p.m. with the occasional daytime marathon.
