Much of the media that Hall referred to was television and movies. The shift to network communication likely creates forums for challenging a lot of traditionally held stereotypes. Just as one example I came across this web series called “Black Folk Don’t”. Every webisode focuses on one stereotype about black culture, and subtly challenges viewers to think about the way they construct their identities and how some stereotypes create self-fulfilling prophecies. The clips are entertaining, and often thought-provoking.
