It’s good to know Orwell, but it’s better to read more. I recommend:
* “Neuromancer,” “Count Zero,” and “Mona Lisa Overdrive,” by William Gibson.
* “The Stars My Destination,” by Alfred Bester. (Also, unrelated, but his book “The Demolished Man” is equally fast-paced and full of awesome.)
* “Market Forces,” by Richard Morgan.
* “Brave New World,” by Aldus Huxley, of course. (Though more statist than my other examples, it is a satire of American consumer culture.)
* “The Space Merchants,” by Frederick Pohl.
* “The Iron Heel,” by Jack London.
* “Do Androids Dream of Electric Sheep?” by Philip K. Dick (the inspiration for Blade Runner). Really, anything by Philip K. Dick has a marvelously depressing edge.

All of these deal with corporations and/or consumer society with a terrifying grip on society.

… That’s not really where I was going with that. The line of thinking I was following was the companies in question eventually buying countries as well (‘countries’ falling under the umbrella of ‘everything in the world’ last I checked) at which point they’d become the government. But thanks for assuming that I’d missed the point of the novel because I made a joke that twisted the backstory ever so slightly.
