Comedy from WikiPedia:

Comedy (from the Greek ???????, komodia) as a popular meaning, is any humorous discourse generally intended to amuse, especially in television, film, and stand-up comedy. This must be carefully distinguished from its academic definition, namely the comic theatre, whose Western origins are found in Ancient Greece. In the Athenian democracy, the public opinion of voters was remarkably influenced by the political satire performed by the comic poets at the theaters. The theatrical genre can be simply described as a dramatic performance which pits two societies against each other in an amusing agon or conflict. Northrop Frye famously depicted these two opposing sides as a "Society of Youth" and a "Society of the Old", but this dichotomy is seldom described as an entirely satisfactory explanation. A later view characterizes the essential agon of comedy as a struggle between a relatively powerless youth and the societal conventions that pose obstacles to his hopes; in this sense, the youth is understood to be constrained by his lack of social authority, and is left with little choice but to take recourse to ruses which engender very dramatic irony which provokes laughter.
