Its a fairly easy subject. You analyze the media, its affects on people, also the way they portray things. Also you analyze structures of movies, advertisements, what they do to make things sell, and that is where usually you will talk a lot about feminisim. You talk a lot about stereotypes, the way they portray races, sexuality, etc. Also, I noticed often it touches on feminism as well. In the end, you are given the tools to be able to analyze things you see on T.V and in the media.
it's easy if you enjoy computer work and well media. It's basicly everything janicee said so if you like doing that you can understand it better than, lets say, someone who likes cullinary.
