Television sitcoms, short for situational comedies, are a genre of television programming that focuses on a fixed set of characters in a consistent setting. These shows typically feature humorous situations and dialogue, often revolving around everyday life and relationships. Popular examples include Friends and The Office, which highlight the comedic aspects of friendship and workplace dynamics. Sitcoms usually have a 30-minute runtime and are structured with a clear beginning, middle, and end, often resolving conflicts by the episode's conclusion. They rely on recurring characters and catchphrases, making them relatable and memorable for audiences. Classic sitcoms like I Love Lucy have paved the way for modern favorites.
