Paper 3 RTV analysis

For my final paper, I want to explore how society uses reality tv shows to make things acceptable that may not have been before. I want to examine the shows Sister Wives, 16 and pregnant, and Real World. These shows air on TLC and MTV. My questions are how society reacted to these shows? How these shows are used to bring awareness to things that weren't publicized before? And how have they changed our outlooks?
