I think you answered your own question. It was promoted as the norm on TV thus it became the norm in society.
The thing about most TV and movies in general is sensationalism. It would be very boring to watch a TV show where people sit on the couch and stare at a TV screen and say nothing and do nothing. Those characters have to be doing something that holds an audiences attention. And sure, as far as storytelling goes, there are acceptable breaks from reality, such as not watching Ward Cleaver take a shit after his morning coffee, we can still relatively safely assume that he does such things despite not being literally and explicitly shown during the program. So, a certain level of breaks from reality are tolerable, but News does the same damn thing. Dammit, I spilled a bit of coffee. If News were to talk about it, they would have to find a way to make a big deal out of it in order to hold the attentions of their audience.
I think what has happened is similar to a "War of Escalation". What happens in News, Stories, Movies, etc, is the version of reality they have is just one step above what actually exists in society. It has to be a bit more interesting than real life, otherwise they lose viewership. The problem is that when they step it up a notch each time, society accepts that level of crazy as the new norm, and media in general again has to escalate one more additional step above the newly redefined level of crazy.
We dont get TV shows about a cop who has "normal day after normal day", thus, not having to issue tickets are arrest anyone because people have behaved themselves and the cop acts like a boring person. The show would absolutely flop. What we get is the cop having to investigate the most heinous murders and crimes. Next problem is that it has to happen every episode in order to maintain a level just above the current level of crazy. So that level of crazy becomes our new normal, so next season, the way the crimes are committed that hero cop investigates has to become even more insane. For example, Murder She Wrote. Old TV show. The town the main character lived in had a population that was so small that at the end of the run of the show, the entire population would fall into one of several categories: murdered, murderer, useless cop, witness, or the hero. The number of deaths and criminals exceeded the population of the lead characters town.
Lastly, its called PROGRAMMING for a reason...
