Walmart teams up with homeland security to install telescreens in 600 walmarts, in 27 states in order to broadcast homeland security public service announcements like this one:

Homeland Security Walmart Public Service Announcement

“It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself–anything that carried with it the suggestion of abnormality, of having something to hide. In any case, to wear an improper expression on your face…; was itself a punishable offense. There was even a word for it in Newspeak: facecrime…”
- George Orwell, 1984

“There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all the time. But at any rate they could plug in your wire whenever they wanted to. You had to live—did live, from habit that became instinct—in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.”
- George Orwell, 1984

“WAR IS PEACE
FREEDOM IS SLAVERY
IGNORANCE IS STRENGTH.”
- Big Brother Slogan
- – George Orwell, 1984
