People often forget how innovative this show was when it first appeared on TV 40 years ago, why was it so innovative? well, for starters it was a comedy anthology show, which has never been done before up until it came out, and it was hour long, while most comedy shows before Love American Style were restricted to the half hour sitcom format (except for the Variety Sketch Comedy Shows such as Carol Brunnet and the Smothers Brothers),. Also, most episodes of the series were filmed neither with a laugh track or a live studio audiance, so it set the standard for many of the comedy shows we see today, such as Modern Family or the Office.
in Conclusion, Love American Style had a Fantastic concept for a show of it's time and it shouldn't be forgotten today. it's a shame it's not on TV anymore (at least it's on DVD finally)
