Situational comedies, often referred to as sitcoms, are a genre of television shows that focus on a fixed set of characters in a consistent setting. The humor typically arises from the characters' interactions and the everyday situations they encounter. Common themes include family dynamics, friendships, and workplace scenarios. These shows often feature a laugh track or live audience to enhance comedic moments. Popular examples of sitcoms include Friends, The Office, and Seinfeld. The format usually involves episodic storytelling, where each episode presents a new challenge or situation for the characters to navigate, often leading to humorous resolutions.
