I used to watch quite a lot of them!
I was more into general knowledge trivia type programs, rather than the ones that are more like a game with a quiz tacked on, if that makes sense. My partner quite enjoyed those. We used to really enjoy one called pointless, where you had to find the most obscure answer to a question, but we stopped watching that after one of the hosts done some disagreeable things towards a marginalised community.
I haven't watched any quizzes in quite some time because I can't watch live TV now, so I rarely turn the on tv anymore, unless it's to watch something on Netflix or Prime.
