Oh, I didn't know that, thank you!
I can now say I didn't like the live studio audience and be more accurate...
It's hard to imagine all of their locations just being sets in a studio! That show was really a technical marvel!
As per usual for the live audience, the sets were in front of the audience and the location stuff was played for the audience on a screen so they could capture their authentic laughs.
But I understand, canned or not, the laughter can seem annoying. It never bothered me one way or the other but I can see how it might.
