American sitcoms, or situational comedies, are a popular television genre that focuses on a fixed set of characters in a consistent setting. These shows typically use humor to explore everyday situations, relationships, and social issues. Classic examples include Friends, The Office, and Seinfeld, which have become cultural touchstones. Sitcoms often feature a laugh track or live audience to enhance comedic moments. They usually follow a formulaic structure, with episodes resolving conflicts or misunderstandings by the end. This format allows for character development and recurring themes, making them relatable and enjoyable for viewers of all ages.
