I enjoy listening to the odd podcast or two, and have been hunting for a while for a really good Quiz/Trivia based podcast and recently came across Minds Over Matter which is an American show, pretty sure its San Francisco based, which airs for one hour each Sunday and seemingly has been doing so for over 20 years.
I have listened to around 4-5 episodes now and have been really enjoying it. It's ad free if you listen on the podcast and every episode as a ton of great questions to get stuck into. Callers phone in with trivia, questions are left open and it runs at a really good pace. Yes, there are several questions which are just "too-trivial" and naturally a lot of US-based stuff I can't get anywhere near, but the core of each show has some great questions and I have been learning a ton from each episode.
Well worth a listen to!
