"with an audience laughing along at everything anyone said or did"

Canned laughter tracks are frequently used in comedy shows in order to accentuate comic scenes and provoke a reaction from the audience.  Some shows were in fact recorded in front of a live audience, which was the source of the laughter track.  It was first used in 1950 in The Hank McCune show, and is now falling out of fashion as most TV producers prefer not to dictate when the audience should laugh.
