In the myth of Oedipus, Oedipus is the son of King Laius and Queen Jocasta. King Laius knew of a prophecy in which his son would end up killing him, which led to him abandoning him to die on a mountainside. However, he was adopted, and when he grew older, he killed his biological father (without knowing his identity). After confronting the Sphinx and defeating it, Oedipus earned the hand of the widowed Queen, Jocasta, who was his biological mother. Upon realizing what had happened, many years later, Oedipus blinds himself. The irony is that when Oedipus became able to "see" the truth, it led him to lose the ability to "see" literally.
The media has all control over society. Everyone is addicted to it. That means they can say whatever they want and people will believe it. If all media sources fell into the hands of one person or group they make things up that are crazy. If they make things up that are crazy people will all watch it. Most of the people will believe this. With more people watching it, they make more money. It's possible they might tell the truth, but that's a low percent.
