Paid stream media
A crew of people, a company, or a weirdo who pay the news to lie to you. They keep telling the same old lie so loud, you start thinking it's true, even though it's total garbage.
A news channel says the president is a chicken, and now people believe it.
A company says your cat is a superhero, just to sell more cat food.
A kid says the teacher is a robot, and now everyone believes it.
