Who has won a million dollars on game show?

It's impossible to say definitively who has won a million dollars on a game show without more context. There are many game shows across different countries and throughout history, and many have offered million-dollar prizes.

To give you a more specific answer, I need more information. For example:

* What game show are you interested in? (e.g., "Who Wants to Be a Millionaire", "Jeopardy!", "Deal or No Deal")

* What country are you interested in? (e.g., United States, United Kingdom, Canada)

* What time period are you interested in? (e.g., current winners, past winners)

Once you provide me with more context, I can help you find the answer!
