This document provides an overview of the history and evolution of the romantic comedy genre. It discusses the origins of rom coms in Shakespearean plays and early 20th century films. It then outlines different subgenres that developed over time, such as comedies of manner in the 1930s, screwball comedies in the 1930s focusing on fast-paced dialogue, and sex comedies from the 1950s-1970s highlighting differences between men and women. Radical romantic comedies in the 1960s focused on personal happiness rather than relationships. Recent neotraditional rom coms emphasize compatibility and compromise. Key conventions, directors, actors, and top-grossing films are also mentioned to analyze trends in the genre.
