... in front of QI last night, it struck me that in almost all panel games and comedy quizzes of this kind, on radio or TV, there is only ever one woman "contestant". Not only QI, but The News Quiz/Have I Got News For You, Just A Minute, Never Mind the Buzzcocks (so it's not just the BBC), whatever.
I'm sure that in the prim and conservative 1950s, programmes like Twenty Questions and What's My Line routinely had two men and two women taking part.
Is this something to do with a change in the perceived audience? But doesn't that become a self-fulfilling prophecy?
