Go is an American television game show created by Bob Stewart and aired on NBC from October 3, 1983, to January 20, 1984. The show featured two teams, each composed of four contestants and a celebrity. The teams had to construct questions one word at a time to convey a word or phrase to their teammates. The concept of "Go" was based on "Instant Reaction", an endgame played on two different versions of another game show created by Bob Stewart, "Chain Reaction" (in 1980 on NBC and from 2006 to 2007 on GSN).
