The genre of romantic comedies began in the early 1930s with films like Trouble in Paradise, building on conventions from Shakespearean comedies featuring romance plots. Typical rom-coms follow a "meet cute" structure where the future couple meets awkwardly or amusingly at the start and their romance develops over the film. In the 1990s, rom-coms took a new direction with films like When Harry Met Sally featuring more sexually charged narratives. Modern studios now experiment with sub-genres and complex topics while maintaining the typical happy ending.
