This is not about the idea of, or general use of canned laughter. It's been proven to work. But has anyone else noticed how STRANGE some of the canned laughter sounded on sitcoms in the 60's and 70's? To begin with, they were taken from old radio shows in the 1940's. (George Carlin once joked that most of the people you hear laughing on sitcoms were already dead.) The really weird thing is the part when it's just a few "mild" laughs. To me it doesn't sound like laughter at all. It doesn't even sound human. It's just really odd. Maybe the first time you heard it, it sounded normal. But to me it's never sounded normal. But I can't believe that people paid so much MONEY for this service. It was in such demand that Hanna Barbera cartoons had to create their own "inferior" version. Hopefully I can find an example of the weird laughter which you have probably heard thousands of times. But this short clip is an interesting history.
