About a decade ago Fox News got brought to court, and had to defend themselves against the idea that their content wasn't actually factually accurate most of the time. Therefore not "news".
Fox responded by saying that their program wasn't meant to be news. I forget the exact quote, I'm sure duckduckgo is your friend, but it was along the lines of "No reasonable person would ever consume Fox News content and believe it to be trustworthy accurate news. It is an opinionated entertainment show about the news."
I don't remember their tagline at the time, but it was something along the lines of "Fox News is your only outlet for unbiased news!" Something to that effect. I just remember Jon Stewart calling out the hypocrasy of their tagline being the exact opposite of what they said in court.
If Fox News is entertainment meant to push the agenda that the right is right, and if CNN is entertainment meant to push the agenda that the left is right, then I don't see why The Onion can't join them as entertainment meant to push the agenda that the whole world is fucking stupid.
Still operating as a "real news source", except it's all bullshit like Fox News and CNN. Just entertainment.
Same thing happened with "VitaminWater", a product in the category of "enhanced water" (a term reminiscent of "enhanced interrogation technique"). Coca-Cola argued that, despite the name, no reasonable person would believe it's actually healthy. They settled.
