This document provides an overview of the history and evolution of sitcoms on television. It discusses how sitcoms originated from radio and vaudeville shows and were popular from the early days of television. Early sitcoms often focused on idealized family situations but then began to reflect changing family dynamics. Career-based sitcoms also emerged. Over time, sitcoms featured more diverse casts and settings and began pushing boundaries through edgier content and non-traditional families/living situations. Sitcom formats continue to adapt to audiences while maintaining elements like recurring jokes, character tropes, and resolving episodes' humorous complications.
