Sitcoms have changed so much over the years amid shifting styles, audience tastes, and improvements in technology. They can be a reflection of what is happening in the world, a unique parallel to the most significant events and movements in history.

The sitcom is a shortened version of the term "situation comedy" and found its origins in radio. Though the first television sitcom aired in 1946, Merriam-Webster dates the first known use of the word to 1956. Sitcoms revolve around a fixed set of characters, with situations carrying over or continuing from week to week, and usually foreground their comedic elements.
