For example, I was in a building once when a natural gas leak caused the roof to blow off. I recorded 3 local news casts about it later that evening. They all got major facts completely wrong. They said it was a warehouse (it was an office building). They said the building was cleared before it blew (I was in it when it blew, the firemen never suggested I leave).

Another one is the 737MAX crashes. The popular press consistently misrepresents and misreports it. (I've posted about that here many times.)

And, quite obviously, the mainstream media in the US has been completely misrepresenting current events. Do you think that's a modern phenomenon? I don't. I suspect it has always been happening, it's just that the internet has exposed it.
