In the latter half of the 21st century, corporations are international financial behemoths - megacorporations. They have their own political aims, even waging more or less open conflicts against the competition. It's no exaggeration to say that corporations are what shapes the reality and life of an ordinary person. Just take a look around.
Every object in your home came off some production line in a factory belonging to one of the megacorps. Another one delivers electricity to your home, so you can watch TV news on a media conglomerate's channel, which in turn has corporations as a majority of its shareholders. Everything you drink, even to a certain extent the air you breathe - it all comes from global concerns.
Even if you're blissfully unaware of this, the corporations still influence every aspect of your life. They're at your fingertips. Ah - those fingers are chrome? What manufacturer? Exactly.
