Sterotypes for each generation

People have sterotypes about every race, sex, and gender. The question is how does it start? What drives people to say what they say about different groups of people. Does this shape how we watch television and movies. The sad thing is it does. This is what entertain people, so when we talked about the show Family Guy and how it may step over its boudries is because it is true. This show has made millions of dollars throwing in lttle side notes that are races and uncalled for. This is excepted in America I feel because there are so many different ethinic groups and races here. So the creaters feel that they would be able to appeal to an audience that like it when they bash other races. I feel if this show were to be broadcasted in other countries I feel the rating and popularity of this show would be much lower than what it is.
