I find these kinds of topics fascinating. Still with me? Okay, cool...
The media and entertainment industry is a beast. However it is a beast that tends to mirrors the wants and desires of the public. There are a ton of medical/cop dramas out there, there are a ton of "reality" shows. There is some truly entertaining a creative stuff in that group but overall the trend gears towards either the grizzly, the mysterious or flat out competition.
"Reality TV" has been going on since the dawn of civilization - see gladitorial fights and their ilk. Comedy and tragedy are two of the most powerful forms of theme in entertainment and reality based shows feed off of that - the emotions and reactions of the people who we've usually never seen before. The ultimate voyueristic experience: there are no drawbacks, no chance of getting "caught."
A violent society (which one could argue both ways as to what we are) propagates more violence. Where is this all going? Well, to shows like "Running Man" for starters. Yeah, that was a cheeky sci-fi Arnie flick but there is some merit to it. It hails back to the gladitorial arenas of old and satisfies the public's desire for intense drama. Sure there would be outcrys against a show like that and it would take someone in great power to get it on the air (either that or some radical change in the world/government) but that is one potential direction that this kind of entertainment is heading.
So, you may want to ask yourself: Would you watch Survivor if the people were truly surviving? Against wild beasts, natives, the elements and themselves. There would be death and gore but the producers could edit it to a tolerable point. I think a great amount of people would say yes.
Do I truly think this is where this is all heading? I don't know - but I do know that it is a possible direction. And that is a bit scary.
