Jackpot! is a television game show seen in three different runs between 1974 and 1990. Geoff Edwards hosted the original version of this Bob Stewart production from January 7, 1974 until September 26, 1975 on NBC. A second version, produced in Canada, aired from September 30, 1985 to December 30, 1988 on the USA Network in the U.S. and was hosted by Mike Darrow. A third version, again hosted by Edwards, ran from September 18, 1989 to March 16, 1990 in syndication and was filmed in Glendale, California. Elements of Jackpot! were later used in the GSN game show Hollywood Showdown. Its producer, Sande Stewart, became a production partner of his father during the 1980s.
