- Martin Esslin coined the term "Theatre of the Absurd" in his 1962 book to describe plays that defied traditional genres, such as Samuel Beckett's Waiting for Godot. - Waiting for Godot premiered in 1953 and became hugely popular despite having no plot, repetitive dialogue and action, and an unexplained ending. - Characteristics of absurd plays include hopelessness, absurd or unexplained endings, comic scenes, repetition, and elements of existentialism which questions the existence and purpose of man.
