1950's game named after a very popular radio and television show at that time. The programme consisted of questions (by post and by an audience watching the recording) and a panel of four academics would answer them. Not a quiz show, it was just deemed by the BBC that it would educate the country (which, in the BBC's mind, needed educating). The game is an electronic trivia type where players are asked questions and then plug the sensor into a hole in the question sheet. If they are wrong, nothing happens, but if they are right a bulb lights up.
