It's amazing how many people have zero hobbies outside of just sitting in front of the TV all night and all weekend. Got rid of mine 10 years ago - apart from the fact I was paying for output 99% of which was just completely unwatchable junk, I could not stand another second of the jingles, trailers, ads and other "filler" which they bombard you with. It really feels like wading through trash.
I think TV culture affects mass psychology in a big way. Today's junk reality shows, for instance, are turning people into some of the most insufferable douchebags in human history. And I wouldn't mind betting that it's making them more aggressive too. Reality TV is full of these fake "confrontations" in which people go tooth and claw at each other, safe in the knowledge that it's in front of the camera and thus potentially millions of witnesses should anything get out of hand. And so idiots are adopting the same kind of confrontational actions and body language in real life, only things get a little more serious when there's no camera crew around to make people think about consequence.
I truly believe that if everyone got rid of their TV's the world would be a better place.
Monkey see, monkey do... It's pretty incredible when you take a step back to see just how much people will imitate what they see and hear, even speech patterns and intonation. Ever heard of that speech trend called "vocal fry"?
I don't watch TV but I do watch series on the net - Star Trek and stuff. The minute the commercial break starts I hit mute. And this allows me to focus on mannerism, and how people just mimic one another and how even corporal expression has been brought down to a set of clichés.
As for the rest, if you put something on tv, you make it legitimate. I remember I first noticed that way back when a show back home mocked common flaws among us back there. But instead of getting people to change, it actually made those flaws even more common, dare I say trendy. People gave in and indulged 100%, and adopted the idioms of that show, going as far as mimicking the comedians speech patterns and accents.
