An interesting case (from a book which I unfortunately can’t remember the name of) from when Jack Benny’s career transitioned from radio to tv: he hated the laugh track, so much so that he demanded it be cut way back and lowered in volume. He also utilized it in an unexpected way: when he had a live audience in certain cases, if a joke or gag got an unexpected big laugh that he didn’t think deserved the reaction, he’d fill in a laugh track with a more muted response.
