Information Please is an American radio quiz show, created by Dan Golenpaul, which aired on NBC from May 17, 1938, to April 22, 1951. The title was the contemporary phrase used to request from telephone operators what was then called "information" and later called "directory assistance".
The series was moderated by Clifton Fadiman. A panel of experts would attempt to answer questions submitted by listeners. For the first few shows, a listener was paid $2 for a question that was used, and $5 more if the experts could not answer it correctly.
