> Same goes for anyone giving a public speech, their cadence and tone would sound bizarre if they were just say in a room with you.
Then imagine these newscasters giving a public speech in that same way. You'd think you had stepped into the quarterly meeting of psychotics planning a spree.
EDIT:
And most importantly in my living room example: That's where the TV is. If you wouldn't invite a person in the flesh and blood to your living room to behave like this, why would you invite them through your TV?
What about true crime and murder series on Netflix? Who would want to spend their evenings with a flesh and blood person in their bedroom who would go on into gory details for hours about murders and abductions? But still people invite these reptilians to their bedrooms through the TV.

is most famous for his book The Media Monopoly but his obscure 1971 book The Information Machines: Their Impact on Men and the Media was highly predictive of what news on the web was going to look like because he had worked for the RAND corporation and tried to sell a very unprogressive (in terms of business) media interest on the idea of online personalized news and they didn't want to make the investment.
That book has some of the most damning indictments of the concept of "news" from a McLuhanite perspective that ever been put to writing, most of all a description of how the editor of a small-town newspaper has about 6 seconds to look at a newswire story and decide if he wants to run it. It's a fundamental act of violence against the framework of reality to throw out 99.999% of it and the kind of "bias" that people get stuck on where people think we need an equal balance of stories that infuriate right-wingers and infuriate left-wingers.
