How long has this show had a laugh track? I'vve been watching foor seven seasons, and never noticed it until tonight. Maybe because it's not as intrusive as Big Bang Theory's.
How I Met Your Mother has always been a pre-recorded multi-camera setup to simulate the standard 3-camera format that most sitcoms use (except Scrubs). The taped episodes are then shown to a studio audience to capture the laughter. So its not a laugh track so much as its a post-episode live audience.
Big Bang Theory uses the traditional 3-camera format, but has a live studio audience.
I don't think shows use "laugh tracks" anymore.
