You have got a point, but I can answer your question as well.
TV and Film. As a media institution, they are afraid of new ideas and will stick with the classic formulas because of this. I mean has anyone seen a horror moive recently? The formulae for all of them is almost exactly the same. But then again, maybe its because horror as a genre is very formulaic. I don't know I'm just your simple, average run of the mill Media Student.
Also as a market, Film and TV are incredibly saturated. You have certain digital providers offering over 700 channels, with only 1 in 50 ever producing a good or worthwhile piece of film or TV. Then you have the HUGE EFFECTS AUDIENCE THAT EAT EVERYTHING SPOON FED CRAP WATCHING TV!!! (Really don't like that theory.) These people don't like anything out of the box or different from the hegemony.
Now that's not to say that its all worthless. You have got series like True Blood that are finally getting some credit, or the one about the detective that hunts serial killers and kills them. (Forgot the name of that one.)
Here in the UK we have one advantage over the rest of the world. (Big up the UK!
) We have the BBC. A publicly owned broadcaster that produce TV series, Documentaries and Films not for ratings, but to entertain their audience. The BBC doesn't make any money from ratings, as it legally can not advertise, because its owned by the public. It gives its producers free reign on what they write or procure to a point. I mean there is an amazing TV series that is currently beginning the filming of its second called Being Human. Its about three essentially dysfunctional people living in a house, the twist? Ones a vampire, trying to stop taking blood, the another a werewolf with confidence issues and the lasts a ghost that can't leave the house.Quite dark with some humour. I love it. Now the BBC has flaws. I'll admit, and it is far from perfect, but it is something that make me very proud.
