Within this Post-Modern Sphere I Wander

Upon examination, the heavily permeating media within our society matches up with the idea of post-modernism, and for the purpose of this writing I shall make the assumption that the world is indeed post-modern. So let us look upon that which is fed to our eyes.
"The Media," that incredibly vague term that describes anything to do with information transfer, has become an incredibly powerful force within the world. America has based both commercialism and politics around it, running ads nonstop via the internet and television. Advertisements are not descriptions of products or explanations of various political plans, but sales pitches created for the sole purpose of convincing you that doing what they say is a really good idea. The people making the commercial don't particularly care if the politician is inept or the cure-all is a sugar pill, so long as people buy into it. The entire basis of this type of advertisement is the idea that convincing people by any means necessary is more important than giving honest sentiment.

This constant influx of attempts at winning you over muddies the water of what can be considered the "truth", because of the thousands of ideologies presented in thousands of different ways. This means that whether you believe in absolute truth or not, every assertion made should be taken with a grain of salt, to avoid believing something with no reasoning. Politician A has mudslingers churning out black and white ads with somber music, explaining why politician B is just the worst person, pointing out anything they've ever done that could be twisted into a flaw. Truth is irrelevant, the job is to get people to believe it. To forge an image that will stick in peoples minds, influence their every decision, make them dance like a puppet.

Each individual message wouldn't have much of an effect alone, if every one contradicted all the others. However, the true ideologies are created when the majority of "the media" all use the same tropes, all claim the same reality. This bombardment of the same idea impresses into our mind an image of what life is, which in turn reinforces our belief in the very ads and shows that created the notion. Thus is the cycle of post-modernism. An ideology reinforces an ideology that reinforces that ideology. We stare into two mirrors facing each other, and take it as reality.
