Expedition Unknown
originally aired on truTV
Expedition Unknown premiered on January 8, 2015, on the Travel Channel and broadcast seasons 1-4. At the start of the 5th season in 2018, the series moved to the Discovery Channel, which became its new home. In February 2020, a spinoff Expedition X premiered on Discovery, which focuses on paranormal subjects. In May 2021, Gates and camera operator Brian Weed visited OceanGate CEO Stockton Rush to test out the Titan submersible, with plans to eventually film a dive to the Titanic wreck on the Titan for an episode of Expedition Unknown. Gates asked the network to cancel the planned episode, and the Titan later imploded in 2023, killing four others.
