Something I've seen on newsmagazine shows here in the US like Dateline NBC. When they want to portray something as having happened in the past using "re-enactment", or older actual videotape of something, they like to overlay it to make it look like scratchy, spotty, really dirty, film camera footage. That drives me nuts. It just accentuates the "infotainment" aspect and degrades any sense of serious journalism. One guy on Dateline, Keith Morrison, uses tone of voice to imply who the dishonest/guilty/lying/etc. party is. Very scummy.
When my television died last year I didn't replace it. I'm better off without the dreck and drivel on TV these days. If there's something truly newsworthy, I can watch it online, anyway.
