Since 1987, various companies have cashed in on the success of Jeopardy by releasing video games based on the TV Quiz Show.
Host Alex Trebek has participated in the games since 1992.
Announcer Johnny Gilbert has also participated in the games early on but his voice is only heard in the game's intros by saying This...is Jeopardy! but it wasn't until the late 1990s/early 2000s when his role in the video games expanded when he (not Alex) would read the answers in the Jeopardy! and Double Jeopardy! rounds.
Clue Crew member Kelly Miyahara has participated in the Jeopardy! games since 2010.
Clue Crew members Jimmy McGuire and Sarah Whitcomb-Foss have participated in the Jeopardy! video games in 2012.
