That's an interesting question. My recollection is that while they were slowly changing over the last 10 or 15 years, the last 4 years, so starting in early 2016, they went radically dark. It's like an evil spell was cast on them all at the same time, like the order went out from the Eye of Sauron. The appearance of Trump was the catalyst. I have no doubt, because of the simultaneous & radical change of all MSM save the few conservative sites, that there was an actual order from an actual person or organization to them all to go into propaganda mode. That this is true can be seen almost every day when a new talking point goes out from the evil Eye, every single talking head says exactly the same talking point as every other one across the field of TV news, like they're all robots. Greg Gutfeld is particularly adept at stitching them all together to display to all the viewers that there's a big puppet master somewhere controlling everything we hear. It's like a nightmare come true. There's no other way to reasonably explain what happened. And that means that there's a huge, powerful, rich someone who has incredibly evil plans to seize control of western nations. Bill Barr needs to realize this & respond accordingly. We cannot lose this battle. If we lose, the entire world falls with us.
