There's some epic rose tinted glasses going on there.
I remember living through the IRA bombings.
And then 9/11
There wasn't a whole huge amount of happy stories going on. You want to know why? Cos there was big shitty stories actually going on that needed reporting. You know like a massive elephant in the room called Iran.
I am guessing the 1970s and the fuel crisis and the very warm summer of 76s the news wasn't much of a barrel of laughs either. That's before I was born so I don't know, but I have my suspicions.
I am also guessing that 1939 - 45 weren't a particularly cheerful time in the news either. Damn the miserable journalists for not being more cherry.
Given that newspapers were a feature of the emergence of the French Republic and the Independence of the USA (technology change helped to cause social unrest amazingly enough) I'm fairly sure the whole history of the media and news has been based on fairly miserable reporting.
I'm a media studies graduate... This argument about cheerful media really isn't going to wash with me. This is about you wanting to bury your head in the sand and disconnect from the reality of the world around you. This is about not wanting to burst your bubble of the world you are in now being 'nice'. Not that the media has somehow got more miserable.
You don't want to see that it's not nice because if you do, you might be forced to process it.
