Queer theory emerged in the early 1990s to explore and challenge the construction of heterosexuality as normal and the limited representations of LGBTQ people in media. It suggests that gender and sexuality exist on a fluid spectrum rather than rigid categories. Queer theorists analyze how media texts either disrupt or reinforce social norms around gender and sexuality through characters like flamboyant Captain Jack Sparrow or the complex relationship between Joey and Chandler. Representations have become more diverse over time, though some argue they still rely on shock value rather than a desire to promote diversity.
