At this point, it seems like sitcoms have explored every avenue possible, and have become so full of overdone tropes that they're just not as successful of a TV genre as they used to be. There haven't been many sitcoms in recent years that have hit the heights of popularity that shows like Friends or How I Met Your Mother did. A lot of people have brought attention to the harmful tropes that often get repeated in these shows, and many criticize the very idea of a laugh track, stating that it makes a joke less funny when the show has to tell the audience when to laugh.
