Sitcoms are a genre of comedy that uses recurring characters and common settings like homes, workplaces, or pubs. They contain elements of both drama and humor to create comedic but situational stories. While older sitcoms may be suitable for all ages, more recent sitcoms often contain mature content and are generally intended for viewers 16 and older. Famous examples include Only Fools and Horses about two brothers pursuing wealth, and The Office about the humor of a typical workplace. Sitcoms are characterized by their use of recurring themes like family, workplace, or groups of friends in humorous situations.
