he didnt mention the program, its a theory that we're all being watched, the shows only been on since 1999 somewhere in europe (netherlands or somewhere :S) and since 2000 in the UK
The first UK Big Brother was in 1999 so its been going for nine years.
The concept originated in the Netherlands.
What George Orwell was talking about was a "Big Brother" society where everyone knows everyone else's business. He wasn't talking about the Big Brother tv show as it hadn't been invented then.
