The game show with the biggest jackpot in U.S. history was "Who Wants to Be a Super Millionaire?" The show was a 12-episode spin-off of "Who Wants to Be a Millionaire?" which ran in February and May 2004 and offered contestants the tantalizing possibility of going home $10 million richer.
The structure of the show was almost identical to the original, right down to its host, Regis Philbin, but none of the contestants ever came anywhere close to winning the record jackpot. The biggest winner was computer specialist Robert Essig, who won $1 million, a mere 10 percent of what could have been taken home.
