Paid stream media
A group of people, a company, or a total idiot who pay the news to lie to you. They say the same stupid thing over and over until you think it's real, even though it's complete trash.
A news channel says the president is a monster, and now people believe it.
A company says your dog is a superhero, just to sell more dog toys.
A kid says the school is haunted, and now everyone believes it.
