1976, as a run-up to a new version of the show called The $128,000 Question, which ran for two years. The first season was hosted by Mike Darrow and produced at the Ed Sullivan Theater in New York City, while the second was produced at Global Television Network in Toronto, Ontario, Canada and hosted by Alex Trebek. In 1999, television producer Michael Davies attempted to revive Question as The $640,000 Question for ABC, before abandoning that project in favor of producing an American version of the British game show Who Wants to Be a Millionaire?. Millionaire has a very similar format to The $64,000 Question – 15 questions in which the contestant's money roughly doubles with each correct question until reaching the top prize. However, the questions in Millionaire are of a broader variety than Question's one-category line of questioning and have a different category for each question, all questions are multiple choice, contestants are allowed to leave the game with their money after a question is revealed but before it is answered, and Millionaire offers three chances for help (called "lifelines"), which were not present in Question. In 2000, responding to the success of Millionaire, CBS bought the rights to the property in a reported effort to produce another revival attempt, The $64,000 Question (with a top prize of $1,024,000), to be hosted by sportscaster Greg Gumbel. Because of format issues similar to those encountered by Davies for ABC, this version was never broadcast.

International versions Australia A similar version of The $64,000 Question was successful in Australia from 1960 to 1971 on Seven Network.
