Yes yes and yes!! And not just TV but corporate media in general. First time we experienced this personally first-hand was over 30 years ago when we came out for Greenham Common "Arms Around the Base"; an unforgettable (rich amazing; people from all walks of life), multi-generational outpouring of humanity for humanity. Our two daughters were just emerging from childhood into teen. They were so excited to stop at the service station on the way home and "see us all" in the big newspapers. It was shocking how every newspaper spun a bias to make the turnout seem totally fringe, a little bunch of weird people that don't represent 'society'. The best thing about that affront was that it was monumental for our young daughters; such disingenuous reporting alerted them to the inherent bias in mainstream media early in life; a media vested in some status quo/monied agenda that proactively works to dissuade the populace away from anything that might undermine business as usual.
