10. Jeopardy!
Although there have been breaks in the run, the game show Jeopardy! which first broadcast March 1964 on NBC, still airs today. The brainchild of Merv Griffin, the game show enjoyed a decade of fanaticism over its unique format, where the correct question was the correct answer. Over the decades, Jeopardy! has won over 30 Daytime Emmy Awards. Syndication of the show today crosses international borders. There’s even a Japanese version.
