You can read more about the CBS Television Quiz in my Television Programs in 1941 article. In short, the hour-long quiz show premiered on Wednesday, July 2nd, 1941 (the day after commercial broadcasting officially began) and ran from 8:30-9:30PM. Gil Fates served as host and Frances Buss as scorekeeper. It was moved around two during its run and cut down to 55 minutes and later 50 minutes. It's unlikely any footage from the series exists, given that it was broadcast before it became possible to record live television. Pictures could exist, however, and I'd love to see any.
