Book excerpt: This book explores the mechanisms that have driven the evolution of televisual comedy from the classic sitcom, a genre deeply rooted in its theatrical origins, toward a more mature stage of television's history. It analyzes four comic series--Scrubs, The Office, The Comeback, and Ugly Betty--revealing how each separates itself from the traditional sitcom archetype and shows increased awareness of the comic genre. Throughout the author focuses on two cardinal themes: the relationship between comedy and euphoria; and the relationship between comic texts and reality.
