These genre changes reflect larger cultural changes such aschanges in the nature of masculinity (Messerschmidt, 1993), what it means to be a hero(Cavender, 1999), or the fact that there are more women in the criminal justice workplace(Martin and Jurik, 2006).
By showing women and men differently from older crime shows did, CSI tells viewers that authority isn't only about brute strength of traditional gender roles. It shows us that intelligence and competence matter more than old stereotypes.
